General DescriptionThe MAX3230E/AE and MAX3231E/AE are +2.5V to +5.5V powered EIA/TIA-232 and V.28/V.24 communica-tions interfaces with low power requirements, high data-rate capabilities, and enhanced electrostatic discharge (ESD) protection, in a chip-scale package (UCSP™)and WLP package. All transmitter outputs and receiver inputs are protected to ±15kV using IEC 1000-4-2 Air-Gap Discharge, ±8kV using I EC 1000-4-2 Contact Discharge, and ±15kV using the Human Body Model.The MAX3230E/AE and MAX3231E/AE achieve a 1µA supply current with Maxim’s AutoShutdown™ feature.They save power without changing the existing BIOS or operating systems by entering low-power shutdown mode when the RS-232 cable is disconnected, or when the transmitters of the connected peripherals are off.The transceivers have a proprietary low-dropout trans-mitter output stage, delivering RS-232-compliant perfor-mance from a +3.1V to +5.5V supply, and RS-232-compatible performance with a supply voltage as low as +2.5V. The dual charge pump requires only four,small 0.1µF capacitors for operation from a +3.0V sup-ply. Each device is guaranteed to run at data rates of 250kbps while maintaining RS-232 output levels.The MAX3230E/AE and MAX3231E/AE offer a separate power-supply input for the logic interface, allowing con-figurable logic levels on the receiver outputs and trans-mitter inputs. Operating over a +1.65V to V CC range, V L provides the MAX3230E/AE and MAX3231E/AE com-patibility with multiple logic families.The MAX3231E/AE contains one receiver and one trans-mitter. The MAX3230E/AE contains two receivers and two transmitters. The MAX3230E/AE and MAX3231E/AE are available in tiny chip-scale and WLP packaging and are specified across the extended industrial (-40°C to +85°C)temperature range.ApplicationsPersonal Digital Assistants Cell-Phone Data Lump Cables Set-Top Boxes Handheld Devices Cell PhonesFeatures♦6 x 5 Chip-Scale Package (UCSP) and WLP Package♦ESD Protection for RS-232 I/O Pins±15kV—IEC 1000-4-2 Air-Gap Discharge ±8kV—IEC 1000-4-2 Contact Discharge ±15kV—Human Body Model ♦1µA Low-Power AutoShutdown ♦250kbps Guaranteed Data Rate♦Meet EIA/TIA-232 Specifications Down to +3.1V ♦RS-232 Compatible to +2.5V Allows Operation from Single Li+ Cell ♦Small 0.1µF Capacitors ♦Configurable Logic LevelsMAX3230E/MAX3230AE/MAX3231E/MAX3231AE±15kV ESD-Protected +2.5V to +5.5V RS-232 Transceivers in UCSP and WLP________________________________________________________________Maxim Integrated Products 1Typical Operating Circuits19-3250; Rev 1; 10/08For pricing, delivery, and ordering information, please contact Maxim Direct at 1-888-629-4642,or visit Maxim’s website at .Ordering InformationUCSP is a trademark of Maxim Integrated Products, Inc.AutoShutdown is a trademark of Maxim Integrated Products, Inc.Typical Operating Circuits continued at end of data sheet.Pin Configurations appear at end of data sheet.+Denotes a lead-free/RoHS-compliant package.T = Tape-and-reel.M A X 3230E /M A X 3230A E /M A X 3231E /M A X 3231A E±15kV ESD-Protected +2.5V to +5.5V RS-232 Transceivers in UCSP and WLP 2_______________________________________________________________________________________ABSOLUTE MAXIMUM RATINGSStresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.

For supply voltages above +3.7V, the charge pump generates +5.5V at V+ and -5.5V at V-. The charge pumps operate in a discontinuous mode. If the output voltages are less than ±5.5V, the charge pumps are enabled. I f the output voltages exceed ±5.5V, the charge pumps are disabled.For supply voltages below +2.85V, the charge pump generates +4.0V at V+ and -4.0V at V-. The charge pumps operate in a discontinuous mode. I f the output voltages are less than ±4.0V, the charge pumps are enabled. I f the output voltages exceed ±4.0V, the charge pumps are disabled.Each charge pump requires a flying capacitor (C1, C2)and a reservoir capacitor (C3, C4) to generate the V+and V- supply voltages.Voltage Generation in theSwitchover RegionThe MAX3230E/AE and MAX3231E/AE include a switchover circuit between these two modes that have approximately 400mV of hysteresis around the switchover point. The hysteresis is shown in Figure 1.This large hysteresis eliminates mode changes due to power-supply bounce.For example, a three-cell NiMh battery system starts at V CC = +3.6V, and the charge pump generates an out-put voltage of ±5.5V. As the battery discharges, the MAX3230E/AE and MAX3231E/AE maintain the outputsThe output regulation points then change to ±4.0V.When V CC is rising, the charge pump generates an out-put voltage of ±4.0V, while V CC is between +2.5V and +3.5V. When V CC rises above the switchover voltage of +3.5V, the charge pump switches modes to generate an output of ±5.5V.Table 1 shows different supply schemes and their oper-ating voltage ranges.RS-232 TransmittersThe transmitters are inverting level translators that convert CMOS logic levels to RS-232 levels. The MAX3230E/AE and MAX3231E/AE automatically reduce the RS-232-compliant levels (±5.5V) to RS-232-compat-ible levels (±4.0V) when V CC falls below approximately +3.1V. The reduced levels also reduce supply-current requirements, extending battery life. Built-in hysteresis of approximately 400mV for V CC ensures that the RS-Figure 1. V+ Switchover for Changing V CC6V4V20ms/divV CCV+Dual Mode is a trademark of Maxim Integrated Products, Inc.MAX3230E/MAX3230AE/MAX3231E/MAX3231AE232 output levels do not change if V CC is noisy or has a sudden current draw causing the supply voltage to drop slightly. The outputs return to RS-232-compliant levels (±5.5V) when V CC rises above approximately +3.5V.The MAX3230E/AE and MAX3231E/AE transmitters guarantee a 250kbps data rate with worst-case loads of 3k Ωin parallel with 1000pF.When FORCEOFF is driven to ground, the transmitters and receivers are disabled and the outputs become high impedance. When the AutoShutdown circuitry senses that all receiver and transmitter inputs are inac-tive for more than 30µs, the transmitters are disabled and the outputs go to a high-impedance state. When the power is off, the MAX3230E/AE and MAX3231E/AE permit the transmitter outputs to be driven up to ±12V.The transmitter inputs do not have pullup resistors.Connect unused inputs to GND or V L .RS-232 ReceiversThe MAX3230E/AE and MAX3231E/AE receivers con-vert RS-232 signals to logic-output levels. All receivers have inverting tri-state outputs and can be active or inactive. I n shutdown (FORCEOFF = low) or in AutoShutdown, the MAX3230E/AE and MAX3231E/AE receivers are in a high-impedance state (Table 2).The MAX3230E/AE and MAX3231E/AE feature an INVALID output that is enabled low when no valid RS-232signal levels have been detected on any receiver inputs.INVALID is functional in any mode (Figures 2 and 3).AutoShutdownThe MAX3230E/AE and MAX3231E/AE achieve a 1µA supply current with Maxim’s AutoShutdown feature,which operates when FORCEON is low and FORCEOFF is high. When these devices sense no valid signal lev-els on all receiver inputs for 30µs, the on-board charge pump and drivers are shut off, reducing V CC supply current to 1µA. This occurs if the RS-232 cable is dis-connected or the connected peripheral transmitters are turned off. The device turns on again when a valid level is applied to any RS-232 receiver input. As a result, the system saves power without changes to the existing BIOS or operating system.Table 2 and Figure 2c summarize the MAX3230E/AE and MAX3231E/AE operating modes. FORCEON and FORCEOFF override AutoShutdown. When neither con-trol is asserted, the I C selects between these states automatically, based on receiver input levels. Figures 2a, 2b, and 3a depict valid and invalid RS-232-receiver levels. Figures 3a and 3b show the input levels and tim-ing diagram for AutoShutdown operation.A system with AutoShutdown can require time to wake up. Figure 4 shows a circuit that forces the transmitters on for 100ms, allowing enough time for the other system to realize that the MAX3230E/AE and±15kV ESD-Protected +2.5V to +5.5V RS-232 Transceivers in UCSP and WLP_______________________________________________________________________________________7MAX3231E/AE are active. If the other system transmits valid RS-232 signals within that time, the RS-232 ports on both systems remain enabled.When shut down, the device’s charge pumps are off,V+ is pulled to V CC , V- is pulled to ground, and the transmitter outputs are high impedance. The time required to exit shutdown is typically 100µs (Figure 3b).V L Logic Supply InputUnlike other RS-232 interface devices, where the receiv-er outputs swing between 0 and V CC , the MAX3230E/AE and MAX3231E/AE feature a separate logic supply input (V L ) that sets V OH for the receiver outputs. The transmit-ter inputs (T_IN), FORCEON, and FORCEOFF , are also referred to V L . This feature allows maximum flexibility in interfacing to different systems and logic levels.Connect V L to the system’s logic supply voltage (+1.65V to +5.5V), and bypass it with a 0.1µF capacitor to GND.I f the logic supply is the same as V CC , connect V L to V CC . Always enable V CC before enabling the V L supply.V CC must be greater than or equal to the V L supply.Software-Controlled ShutdownIf direct software control is desired, connect FORCEOFF and FORCEON together to disable AutoShutdown. Themicrocontroller (µC) then drives FORCEOFF and FORCEON like a SHDN input. INVALID can be used to alert the µC to indicate serial data activity.±15kV ESD ProtectionAs with all Maxim devices, ESD-protection structures are incorporated on all pins to protect against electro-static discharges encountered during handling and assembly. The driver outputs and receiver inputs of the MAX3230E/AE and MAX3231E/AE have extra protec-tion against static electricity. Maxim’s engineers have developed state-of-the-art structures to protect these pins against ESD of ±15kV without damage. The ESD structures withstand high ESD in all states: normal operation, shutdown, and power-down. After an ESD event, Maxim’s E-versions keep working without latchup, whereas competing RS-232 products can latch and must be powered down to remove latchup.ESD protection can be tested in various ways; the trans-mitter outputs and receiver inputs of this product family are characterized for protection to the following limits:1) ±15kV using the Human Body Model2) ±8kV using the Contact Discharge method specified in IEC 1000-4-23) ±15kV using the IEC 1000-4-2 Air-Gap methodESD Test ConditionsESD performance depends on a variety of conditions.Contact Maxim for a reliability report that documents test setup, test methodology, and test results.Human Body ModelFigure 5a shows the Human Body Model.

MAX323_E AutoShutdown LogicMAX3230E/MAX3230AE/MAX3231E/MAX3231AEwhich is then discharged into the test device through a 1.5k Ωresistor.IEC 1000-4-2The IEC 1000-4-2 standard covers ESD testing and per-formance of finished equipment. It does not specifically refer to ICs. The MAX3230E/AE and MAX3231E/AE aid in designing equipment that meets Level 4 (the highest level) of I EC 1000-4-2, without the need for additional ESD-protection components.The major difference between tests done using the Human Body Model and IEC 1000-4-2 is a higher peak current in I EC 1000-4-2, because series resistance is lower in the IEC 1000-4-2 model. Hence, the ESD with-stands voltage measured to IEC 1000-4-2 and is gener-ally lower than that measured using the Human Body Model. Figure 6a shows the I EC 1000-4-2 model, and Figure 6b shows the current waveform for the ±8kV IEC 1000-4-2 Level 4 ESD Contact Discharge test.The Air-Gap test involves approaching the device with a charged probe. The Contact Discharge method connects the probe to the device before the probe is energized.Machine ModelThe Machine Model for ESD tests all pins using a 200pF storage capacitor and zero discharge resistance. I ts objective is to emulate the stress caused by contact that occurs with handling and assembly during manufactur-ing. Of course, all pins require this protection during manufacturing, not just RS-232 inputs and outputs.Therefore, after PC board assembly, the Machine Model is less relevant to I/O ports.Applications InformationCapacitor SelectionThe capacitor type used for C1–C4 is not critical for proper operation; either polarized or nonpolarized capacitors can be used. However, ceramic chip capaci-tors with an X7R or X5R dielectric work best. The charge pump requires 0.1µF capacitors for 3.3V operation. For other supply voltages, see Table 3 for required capaci-tor values. Do not use values smaller than those listed in Table 3. Increasing the capacitor values (e.g., by a fac-tor of 2) reduces ripple on the transmitter outputs and slightly reduces power consumption. C2, C3, and C4can be increased without changing the vaue of C1.Caution: Do not increase C1 without also increasing the values of C2, C3, and C4 to maintain the proper ratios (C1 to the other capacitors).When using the minimum required capacitor values,make sure the capacitor value does not degrade exces-sively with temperature. If in doubt, use capacitors with±15kV ESD-Protected +2.5V to +5.5V RS-232 Transceivers in UCSP and WLP_______________________________________________________________________________________9Figure 3.

The capacitor’s equivalent series resistance (ESR) usually rises at low temperatures and influences the amount of ripple on V+ and V-.Power-Supply DecouplingIn most circumstances, a 0.1µF V CC bypass capacitor is adequate. In applications that are sensitive to power-supply noise, use a capacitor of the same value as the charge-pump capacitor C1. Connect bypass capaci-tors as close to the IC as possible.Transmitter Outputs whenExiting ShutdownFigure 7 shows a transmitter output when exiting shut-down mode. The transmitter is loaded with 3k Ωin par-allel with 1000pF. The transmitter output displays no ringing or undesirable transients as it comes out of shutdown, and is enabled only when the magnitude of V- exceeds approximately -3V.High Data RatesThe MAX3230E/AE and MAX3231E/AE maintain the RS-232 ±5.0V minimum transmitter output voltage even at high data rates. Figure 8 shows a transmitter loop-back test circuit. Figure 9 shows a loopback test result at 120kbps, and Figure 10 shows the same test at 250kbps. For Figure 9, the transmitter was driven at 120kbps into an RS-232 load in parallel with 1000pF.For Figure 10, a single transmitter was driven at 250kbps and loaded with an RS-232 receiver in paral-lel with 1000pF.Figure 6a.

MAX213CAI-T中文资料
General DescriptionThe MAX200–MAX211/MAX213 transceivers are designed for RS-232 and V.28 communication inter-faces where ±12V supplies are not available. On-board charge pumps convert the +5V input to the ±10V need-ed for RS-232 output levels. The MAX201 and MAX209operate from +5V and +12V, and contain a +12V to -12V charge-pump voltage converter.The MAX200–MAX211/MAX213 drivers and receivers meet all EIA/TIA-232E and CCITT V.28 specifications at a data rate of 20kbps. The drivers maintain the ±5V EIA/TIA-232E output signal levels at data rates in excess of 120kbps when loaded in accordance with the EIA/TIA-232E specification.The 5µW shutdown mode of the MAX200, MAX205,MAX206, and MAX211 conserves energy in battery-powered systems. The MAX213 has an active-low shut-down and an active-high receiver enable control.

MAX1324中文介绍
详细描述模拟输入（Analog Inputs）T/H采样保持为了保证各通道输入信号的相位信息，每个输入通道都有一个专用的采样/保持放大器。
使用一个低值源电阻来降低增益误差谐波失真。
对一个输入信号，采样/保持所需要的时间取决与输入源电阻。
如果输入信号的源电阻是个高值电阻，则采样时间以及转换的时间间隔都会增加。
采样获取时间（t1）是芯片获取信号所需的最大的时间。
可以根据以下的公式计算这个获取时间：这里RIN=2.2K欧姆，RS是输入信号的源电阻值，并且t1不能小于180纳秒。
一个阻值小于100欧姆的源电阻对ADC的性能不会有很明显的影响。
为了提高交流输入信号的带宽，可以将输入信号送人一个宽带的能驱动ADC输入并快速稳定的缓冲器。
典型的采样/保持间隔延迟时间是13纳秒。
这个间隔延迟时间使得多达八个信号间的，采样/保持时间在50皮秒的，相关的相位信息得到保护。
图片2展示了一个简化的等价的输入电路，阐述了ADC的采样构架。
输入带宽输入的跟踪电路有一个12MHz的小信号带宽，使得电路可以将高速的暂态干扰数字化，并且在宽带的周期信号测量中在稀疏采样技术下加速ADC 的采样速度。
为了避免高频信号的干扰，建议加入一个低通滤波器。
输入电压幅值范围及保护这系列的芯片提供了正负10V，正负5V，以及0到+5V的模拟电压输入范围。
图片2展示了等价的输入电路。
模拟输入的过电压保护电路为双极性输入器件提供了正负16.5V的故障保护，为单极性输入器件提供了正负6V的故障保护。
这个故障保护电路把器件的输入或者输出电流限制在50毫安一下，在模拟输入的暂时过电压或者过电压的情况下提供一种附加的保护措施。
省电模式（Power-Saving Modes）关机模式（Shutdown Mode）在关机模式下，器件中的模拟和数字电路电源关闭并且器件从AVDD和DVDD流过100微安以下的电流。

The low input capacitance makes these devices ideal for high-speed data lines. The MAX3202E, MAX3203E, MAX3204E, and MAX3206E protect two, three, four, and six channels, respectively.The MAX3202E/MAX3203E/MAX3204E/MAX3206E are designed to work in conjunction with a device’s intrinsic ESD protection. The MAX3202E/MAX3203E/MAX3204E/MAX3206E limit the excursion of the ESD event to below ±25V peak voltage when subjected to the Human Body Model waveform. When subjected to the IEC 61000-4-2 waveform, the peak voltage is limited to ±60V when subjected to Contact Discharge and ±100V when subjected to Air-Gap Discharge. The device that is being protected by the MAX3202E/MAX3203E/MAX3204E/MAX3206E must be able to withstand these peak voltages plus any additional voltage generated by the parasitic board.Applications InformationDesign ConsiderationsMaximum protection against ESD damage results from proper board layout (see the Layout Recommendations section and Figure 2). A good layout reduces the para-sitic series inductance on the ground line, supply line,and protected signal lines.The MAX3202E/MAX3203E/MAX3204E/MAX3206E ESD diodes clamp the voltage on the protected lines during an ESD event and shunt the current to GND or V CC . In an ideal circuit, the clamping voltage, V C , is defined as the forward voltage drop, V F , of the protection diode plus any supply voltage present on the cathode.For positive ESD pulses:V C = V CC + V FFor negative ESD pulses:V C = -V FIn reality, the effect of the parasitic series inductance on the lines must also be considered (Figure 1).For positive ESD pulses:For negative ESD pulses:where I ESDis the ESD current pulse.M A X 3202E /M A X 3203E /M A X 3204E /M A X 3206ELow-Capacitance, 2/3/4/6-Channel, ±15kV ESD Protection Arrays for High-Speed Data Interfaces 4_______________________________________________________________________________________Figure 1. Parasitic Series InductanceFigure 2. Layout ConsiderationsMAX3202E/MAX3203E/MAX3204E/MAX3206ELow-Capacitance, 2/3/4/6-Channel, ±15kV ESD Protection Arrays for High-Speed Data Interfaces_______________________________________________________________________________________5During an ESD event, the current pulse rises from zero to peak value in nanoseconds (Figure 3). For example,in a 15kV IEC-61000 Air-G ap Discharge ESD event,the pulse current rises to approximately 45A in 1ns (di/dt = 45 x 109). An inductance of only 10nH adds an additional 450V to the clamp voltage. An inductance of 10nH represents approximately 0.5in of board trace.Regardless of the device’s specified diode clamp volt-age, a poor layout with parasitic inductance significantly increases the effective clamp voltage at the protected signal line.A low-ESR 0.1µF capacitor must be used between V CC and G ND. This bypass capacitor absorbs the charge transferred by an +8kV IEC-61000 Contact Discharge ESD event.Ideally, the supply rail (V CC ) would absorb the charge caused by a positive ESD strike without changing its regulated value. In reality, all power supplies have an effective output impedance on their positive rails. If a power supply’s effective output impedance is 1Ω, then by using V = I ×R, the clamping voltage of V C increas-es by the equation V C = I ESD x R OUT . An +8kV IEC 61000-4-2 ESD event generates a current spike of 24A,so the clamping voltage increases by V C = 24A ×1Ω,or V C = 24V. Again, a poor layout without proper bypassing increases the clamping voltage. A ceramic chip capacitor mounted as close to the MAX3202E/MAX3203E/MAX3204E/MAX3206E V CC pin is the best choice for this application. A bypass capacitor should also be placed as close to the protected device as possible.±15kV ESD ProtectionESD protection can be tested in various ways; the MAX3202E/MAX3203E/MAX3204E/MAX3206E are characterized for protection to the following limits:•±15kV using the Human Body Model•±8kV using the Contact Discharge method speci-fied in IEC 61000-4-2•±15kV using the IEC 61000-4-2 Air-Gap Discharge methodESD Test ConditionsESD performance depends on a number of conditions.Contact Maxim for a reliability report that documents test setup, methodology, and results.Human Body ModelFigure 4 shows the Human Body Model, and Figure 5shows the current waveform it generates when dis-charged into a low impedance. This model consists of a 100pF capacitor charged to the ESD voltage of inter-est, which is then discharged into the device through a 1.5k Ωresistor.Figure 4. Human Body ESD Test ModelFigure 3. IEC 61000-4-2 ESD Generator Current WaveformM A X 3202E /M A X 3203E /M A X 3204E /M A X 3206EIEC 61000-4-2The IEC 61000-4-2 standard covers ESD testing and performance of finished equipment. The MAX3202E/MAX3203E/MAX3204E/MAX3206E help users design equipment that meets Level 4 of IEC 61000-4-2.The main difference between tests done using the Human Body Model and IEC 61000-4-2 is higher peak current in IEC 61000-4-2. Because series resistance is lower in the IEC 61000-4-2 ESD test model (Figure 6)the ESD-withstand voltage measured to this standard is generally lower than that measured using the Human Body Model. Figure 3 shows the current waveform for the ±8kV IEC 61000-4-2 Level 4 ESD Contact Discharge test.The Air-G ap Discharge test involves approaching the device with a charged probe. The Contact Discharge method connects the probe to the device before the probe is energized.Layout RecommendationsProper circuit-board layout is critical to suppress ESD-induced line transients. The MAX3202E/MAX3203E/MAX3204E/MAX3206E clamp to 100V; however, with improper layout, the voltage spike at the device is much higher. A lead inductance of 10nH with a 45A current spike at a dv/dt of 1ns results in an ADDITION-AL 450V spike on the protected line. It is essential that the layout of the PC board follows these guidelines:1)Minimize trace length between the connector or input terminal, I/O_, and the protected signal line.2)Use separate planes for power and ground to reduce parasitic inductance and to reduce the impedance to the power rails for shunted ESD current.3)Ensure short ESD transient return paths to G ND and V CC .4)Minimize conductive power and ground loops.5)Do not place critical signals near the edge of the PC board.6)Bypass V CC to GND with a low-ESR ceramic capac-itor as close to V CC as possible.7)Bypass the supply of the protected device to G ND with a low-ESR ceramic capacitor as close to the supply pin as possible.UCSP ConsiderationsFor general UCSP package information and PC layout considerations, refer to Maxim Application Note 263,Wafer-Level Chip-Scale Package .___________________UCSP ReliabilityThe UCSP represents a unique packaging form factor that may not perform equally to a packaged product through traditional mechanical reliability tests. UCSP reliability is integrally linked to the user’s assembly meth-ods, circuit-board material, and usage environment.The user should closely review these areas when con-sidering use of a UCSP. Performance through operat-ing life test and moisture resistance remains uncompromised as it is primarily determined by the wafer-fabrication process. Mechanical stress perfor-mance is a greater consideration for a UCSP. UCSPs are attached through direct solder contact to the user’s PC board, foregoing the inherent stress relief of a pack-aged product lead frame. Solder-joint contact integrity must be considered. Table 1 shows the testing done to characterize the UCSP reliability performance. In con-clusion, the UCSP is capable of performing reliably through environmental stresses as indicated by the results in the table. Additional usage data and recom-mendations are detailed in the UCSP application note,which can be found on Maxim’s website at .Chip InformationPROCESS: BiCMOSLow-Capacitance, 2/3/4/6-Channel, ±15kV ESD Protection Arrays for High-Speed Data Interfaces 6_______________________________________________________________________________________Figure 6.

Transition Slew-Rate Circuit_______________Detailed Description The MAX202E–MAX213E, MAX232E/MAX241E consist of three sections: charge-pump voltage converters, drivers (transmitters), and receivers. These E versions provide extra protection against ESD. They survive ±15kV discharges to the RS-232 inputs and outputs, tested using the Human Body Model. When tested according to IEC1000-4-2, they survive ±8kV contact-discharges and ±15kV air-gap discharges. The rugged E versions are intended for use in harsh environments or applications where the RS-232 connection is frequently changed (such as notebook computers). The standard (non-“E”) MAX202, MAX203, MAX205–MAX208, MAX211, MAX213, MAX232, and MAX241 are recommended for applications where cost is critical.+5V to ±10V Dual Charge-PumpVoltage Converter The +5V to ±10V conversion is performed by dual charge-pump voltage converters (Figure 4). The first charge-pump converter uses capacitor C1 to double the +5V into +10V, storing the +10V on the output filter capacitor, C3. The second uses C2 to invert the +10V into -10V, storing the -10V on the V- output filter capacitor, C4.In shutdown mode, V+ is internally connected to V CC by a 1kΩpull-down resistor, and V- is internally connected to ground by a 1kΩpull up resistor.RS-232 Drivers With V CC= 5V, the typical driver output voltage swing is ±8V when loaded with a nominal 5kΩRS-232 receiver. The output swing is guaranteed to meet EIA/TIA-232E and V.28 specifications that call for ±5V minimum output levels under worst-case conditions. These include a 3kΩload, minimum V CC, and maximum operating temperature. The open-circuit output voltage swings from (V+ - 0.6V) to V-.Input thresholds are CMOS/TTL compatible. The unused drivers’ inputs on the MAX205E–MAX208E, MAX211E, MAX213E, and MAX241E can be left unconnected because 400kΩpull up resistors to V CC are included on-chip. Since all drivers invert, the pull up resistors force the unused drivers’ outputs low. The MAX202E, MAX203E, and MAX232E do not have pull up resistors on the transmitter inputs._______________________________________________________________________________________9MAX202E–MAX213E, MAX232E/MAX241E10______________________________________________________________________________________M A X 202E –M A X 213E , M A X 232E /M A X 241E±15kV ESD-Protected, +5V RS-232 Transceivers When in low-power shutdown mode, the MAX205E/MAX206E/MAX211E/MAX213E/MAX241E driver outputs are turned off and draw only leakage currents—even if they are back-driven with voltages between 0V and 12V. Below -0.5V in shutdown, the transmitter output is diode-clamped to ground with a 1k Ωseries impedance.RS-232 ReceiversThe receivers convert the RS-232 signals to CMOS-logic output levels. The guaranteed 0.8V and 2.4V receiver input thresholds are significantly tighter than the ±3V thresholds required by the EIA/TIA-232E specification.This allows the receiver inputs to respond to TTL/CMOS-logic levels, as well as RS-232 levels.The guaranteed 0.8V input low threshold ensures that receivers shorted to ground have a logic 1 output. The 5k Ωinput resistance to ground ensures that a receiver with its input left open will also have a logic 1 output. Receiver inputs have approximately 0.5V hysteresis.This provides clean output transitions, even with slow rise/fall-time signals with moderate amounts of noise and ringing.In shutdown, the MAX213E’s R4 and R5 receivers have no hysteresis.Shutdown and Enable Control (MAX205E/MAX206E/MAX211E/MAX213E/MAX241E)In shutdown mode, the charge pumps are turned off,V+ is pulled down to V CC , V- is pulled to ground, and the transmitter outputs are disabled. This reduces supply current typically to 1µA (15µA for the MAX213E).The time required to exit shutdown is under 1ms, as shown in Figure 5.ReceiversAll MAX213E receivers, except R4 and R5, are put into a high-impedance state in shutdown mode (see Tables 1a and 1b). The MAX213E’s R4 and R5 receivers still function in shutdown mode. These two awake-in-shutdown receivers can monitor external activity while maintaining minimal power consumption.The enable control is used to put the receiver outputs into a high-impedance state, to allow wire-OR connection of two EIA/TIA-232E ports (or ports of different types) at the UART. It has no effect on the RS-232 drivers or the charge pumps.N ote: The enabl e control pin is active l ow for the MAX211E/MAX241E (EN ), but is active high for the MAX213E (EN). The shutdown control pin is active high for the MAX205E/MAX206E/MAX211E/MAX241E (SHDN), but is active low for the MAX213E (SHDN ).Figure 4.

MAX205E/MAX206E/MAX211E/MAX241E Control Pin ConfigurationsTable 1b. MAX213E Control Pin ConfigurationsThe MAX213E’s receiver propagation delay is typically 0.5µs in normal operation. In shutdown mode,propagation delay increases to 4µs for both rising and falling transitions. The MAX213E’s receiver inputs have approximately 0.5V hysteresis, except in shutdown,when receivers R4 and R5 have no hysteresis.When entering shutdown with receivers active, R4 and R5 are not valid until 80µs after SHDN is driven low.When coming out of shutdown, all receiver outputs are invalid until the charge pumps reach nominal voltage levels (less than 2ms when using 0.1µF capacitors).±15kV ESD ProtectionAs with all Maxim devices, ESD-protection structures are incorporated on all pins to protect against electrostatic discharges encountered during handling and assembly. The driver outputs and receiver inputs have extra protection against static electricity. Maxim’s engineers developed state-of-the-art structures to protect these pins against ESD of ±15kV without damage. The ESD structures withstand high ESD in all states: normal operation, shutdown, and powered down. After an ESD event, Maxim’s E versions keep working without latchup, whereas competing RS-232products can latch and must be powered down to remove latchup.ESD protection can be tested in various ways; the transmitter outputs and receiver inputs of this product family are characterized for protection to the following limits:1)±15kV using the Human Body Model2)±8kV using the contact-discharge method specifiedin IEC1000-4-23)±15kV using IEC1000-4-2’s air-gap method.ESD Test ConditionsESD performance depends on a variety of conditions.Contact Maxim for a reliability report that documents test set-up, test methodology, and test results.Human Body ModelFigure 6a shows the Human Body Model, and Figure 6b shows the current waveform it generates when discharged into a low impedance. This model consists of a 100pF capacitor charged to the ESD voltage of interest, which is then discharged into the test device through a 1.5k Ωresistor.S H D N ENOPERATION STATUS Tx 1–400Shutdown All High-Z 01Shutdown All High-Z 10Normal Operation 11Normal OperationAll ActiveAll Active Active1–34, 5High-Z ActiveHigh-Z High-Z High-Z Active*High-Z RxM A X 202E –M A X 213E , M A X 232E /M A X 241EIEC1000-4-2The IEC1000-4-2 standard covers ESD testing and performance of finished equipment; it does not specifically refer to integrated circuits. The MAX202E/MAX203E–MAX213E, MAX232E/MAX241E help you design equipment that meets level 4 (the highest level) of IEC1000-4-2, without the need for additional ESD-protection components.The major difference between tests done using the Human Body Model and IEC1000-4-2 is higher peak current in IEC1000-4-2, because series resistance is lower in the IEC1000-4-2 model. Hence, the ESD withstand voltage measured to IEC1000-4-2 is generally lower than that measured using the Human Body Model. Figure 7b shows the current waveform for the 8kV IEC1000-4-2 level-four ESD contact-discharge test.The air-gap test involves approaching the device with a charged probe. The contact-discharge method connects the probe to the device before the probe is energized.Machine ModelThe Machine Model for ESD tests all pins using a 200pF storage capacitor and zero discharge resistance. Its objective is to emulate the stress caused by contact that occurs with handling and assembly during manufacturing. Of course, all pins require this protection during manufacturing, not just RS-232 inputs and outputs. Therefore,after PC board assembly,theMachine Model is less relevant to I/O ports.Figure 7a. IEC1000-4-2 ESD Test ModelFigure 7b. IEC1000-4-2 ESD Generator Current WaveformFigure 6a. Human Body ESD Test ModelFigure 6b. Human Body Model Current Waveform__________Applications InformationCapacitor Selection The capacitor type used for C1–C4 is not critical for proper operation. The MAX202E, MAX206–MAX208E, MAX211E, and MAX213E require 0.1µF capacitors, and the MAX232E and MAX241E require 1µF capacitors, although in all cases capacitors up to 10µF can be used without harm. Ceramic, aluminum-electrolytic, or tantalum capacitors are suggested for the 1µF capacitors, and ceramic dielectrics are suggested for the 0.1µF capacitors. When using the minimum recommended capacitor values, make sure the capacitance value does not degrade excessively as the operating temperature varies. If in doubt, use capacitors with a larger (e.g., 2x) nominal value. The capacitors’ effective series resistance (ESR), which usually rises at low temperatures, influences the amount of ripple on V+ and V-.Use larger capacitors (up to 10µF) to reduce the output impedance at V+ and V-. This can be useful when “stealing” power from V+ or from V-. The MAX203E and MAX205E have internal charge-pump capacitors. Bypass V CC to ground with at least 0.1µF. In applications sensitive to power-supply noise generated by the charge pumps, decouple V CC to ground with a capacitor the same size as (or larger than) the charge-pump capacitors (C1–C4).V+ and V- as Power Supplies A small amount of power can be drawn from V+ and V-, although this will reduce both driver output swing and noise margins. Increasing the value of the charge-pump capacitors (up to 10µF) helps maintain performance when power is drawn from V+ or V-.Driving Multiple Receivers Each transmitter is designed to drive a single receiver. Transmitters can be paralleled to drive multiple receivers.Driver Outputs when Exiting Shutdown The driver outputs display no ringing or undesirable transients as they come out of shutdown.High Data Rates These transceivers maintain the RS-232 ±5.0V minimum driver output voltages at data rates of over 120kbps. For data rates above 120kbps, refer to the Transmitter Output Voltage vs. Load Capacitance graphs in the Typical Operating Characteristics. Communication at these high rates is easier if the capacitive loads on the transmitters are small; i.e., short cables are best.Table 2.

MAX202CSE中文资料
General DescriptionThe MAX200–MAX211/MAX213 transceivers are designed for RS-232 and V.28 communication inter-faces where ±12V supplies are not available. On-board charge pumps convert the +5V input to the ±10V need-ed for RS-232 output levels. The MAX201 and MAX209operate from +5V and +12V, and contain a +12V to -12V charge-pump voltage converter.The MAX200–MAX211/MAX213 drivers and receivers meet all EIA/TIA-232E and CCITT V.28 specifications at a data rate of 20kbps. The drivers maintain the ±5V EIA/TIA-232E output signal levels at data rates in excess of 120kbps when loaded in accordance with the EIA/TIA-232E specification.The 5µW shutdown mode of the MAX200, MAX205,MAX206, and MAX211 conserves energy in battery-powered systems. The MAX213 has an active-low shut-down and an active-high receiver enable control. Two receivers of the MAX213 are active, allowing ring indica-tor (RI) to be monitored easily using only 75µW power.The MAX211 and MAX213 are available in a 28-pin wide small-outline (SO) package and a 28-pin shrink small-outline (SSOP) package, which occupies only 40% of the area of the SO. The MAX207 is now avail-able in a 24-pin SO package and a 24-pin SSOP. The MAX203 and MAX205 use no external components,and are recommended for applications with limited circuit board space.ApplicationsComputersLaptops, Palmtops, Notebooks Battery-Powered Equipment Hand-Held Equipment Next-Generation Device Features ♦For Low-Cost Applications:MAX221E: ±15kV ESD-Protected, +5V, 1µA, Single RS-232 Transceiver with AutoShutdown™♦For Low-Voltage and Space-Constrained Applications:MAX3222E/MAX3232E/MAX3237E/MAX3241E/MAX3246E: ±15kV ESD-Protected, Down to 10nA,+3.0V to +5.5V, Up to 1Mbps, True RS-232Transceivers (MAX3246E Available in UCSP™Package)♦For Space-Constrained Applications:MAX3228E/MAX3229E: ±15kV ESD-Protected,+2.5V to +5.5V, RS-232 Transceivers in UCSP ♦For Low-Voltage or Data Cable Applications:MAX3380E/MAX3381E: +2.35V TO +5.5V, 1µA,2Tx/2Rx RS-232 Transceivers with ±15kV ESD-Protected I/O and Logic Pins ♦For Low-Power Applications:MAX3224E–MAX3227E/MAX3244E/MAX3245E:±15kV ESD-Protected, 1µA, 1Mbps, +3.0V to+5.5V, RS-232 Transceivers with AutoShutdown Plus™MAX200–MAX211/MAX213+5V , RS-232 Transceivers with 0.1µF External Capacitors ________________________________________________________________Maxim Integrated Products 119-0065; Rev 6; 10/03For pricing, delivery, and ordering information,please contact Maxim/Dallas Direct!at 1-888-629-4642, or visit Maxim’s website at .Ordering Information appears at end of data sheetAutoShutdown, AutoShutdown Plus, and UCSP are trademarks of Maxim Integrated Products, Inc.MAX200–MAX211/MAX213+5V , RS-232 Transceiverswith 0.1µF External Capacitors______________________________________________________________________________________19Ordering Information*Contact factory for dice specifications.M A X 200–M A X 211/M A X 213+5V , RS-232 Transceiverswith 0.1µF External Capacitors Maxim cannot assume responsibility for use of any circuitry other than circuitry entirely embodied in a Maxim product.

General Description
The MAX481E, MAX483E, MAX485E, MAX487E– MAX491E, and MAX1487E are low-power transceivers for RS-485 and RS-422 communications in harsh environments. Each driver output and receiver input is protected against ±15kV electro-static discharge (ESD) shocks, without latchup. These parts contain one driver and one receiver. The MAX483E, MAX487E, MAX488E, and MAX489E feature reduced slew-rate drivers that minimize EMI and reduce reflections caused by improperly terminated cables, thus allowing error-free data transmission up to 250kbps. The driver slew rates of the MAX481E, MAX485E, MAX490E, MAX491E, and MAX1487E are not limited, allowing them to transmit up to 2.5Mbps.
