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. 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.

The first converter uses capacitor C1 to dou-ble the +5V input to +10V on C3 at the V+ output. The second converter uses capacitor C2 to invert +10V to -10V on C4 at the V- output.A small amount of power may be drawn from the +10V (V+) and -10V (V-) outputs to power external circuitry (see the Typical Operating Characteristics section),except on the MAX225 and MAX245–MAX247, where these pins are not available. V+ and V- are not regulated,so the output voltage drops with increasing load current.Do not load V+ and V- to a point that violates the mini-mum ±5V EIA/TIA-232E driver output voltage when sourcing current from V+ and V- to external circuitry. When using the shutdown feature in the MAX222,MAX225, MAX230, MAX235, MAX236, MAX240,MAX241, and MAX245–MAX249, avoid using V+ and V-to power external circuitry. When these parts are shut down, V- falls to 0V, and V+ falls to +5V. For applica-tions where a +10V external supply is applied to the V+pin (instead of using the internal charge pump to gen-erate +10V), the C1 capacitor must not be installed and the SHDN pin must be tied to V CC . This is because V+is internally connected to V CC in shutdown mode.RS-232 DriversThe typical driver output voltage swing is ±8V when loaded with a nominal 5k ΩRS-232 receiver and V CC =+5V. Output swing is guaranteed to meet the EIA/TIA-232E and V.28 specification, which calls for ±5V mini-mum driver output levels under worst-case conditions.These include a minimum 3k Ωload, V CC = +4.5V, and maximum operating temperature. Unloaded driver out-put voltage ranges from (V+ -1.3V) to (V- +0.5V).Input thresholds are both TTL and CMOS compatible.The inputs of unused drivers can be left unconnected since 400k Ωinput pullup resistors to V CC are built in (except for the MAX220). The pullup resistors force the outputs of unused drivers low because all drivers invert.The internal input pullup resistors typically source 12µA,except in shutdown mode where the pullups are dis-abled. Driver outputs turn off and enter a high-imped-ance state—where leakage current is typically microamperes (maximum 25µA)—when in shutdownmode, in three-state mode, or when device power is removed. Outputs can be driven to ±15V. The power-supply current typically drops to 8µA in shutdown mode.The MAX220 does not have pullup resistors to force the outputs of the unused drivers low. Connect unused inputs to GND or V CC .The MAX239 has a receiver three-state control line, and the MAX223, MAX225, MAX235, MAX236, MAX240,and MAX241 have both a receiver three-state control line and a low-power shutdown control. Table 2 shows the effects of the shutdown control and receiver three-state control on the receiver outputs.The receiver TTL/CMOS outputs are in a high-imped-ance, three-state mode whenever the three-state enable line is high (for the MAX225/MAX235/MAX236/MAX239–MAX241), and are also high-impedance whenever the shutdown control line is high.When in low-power shutdown mode, the driver outputs are turned off and their leakage current is less than 1µA with the driver output pulled to ground. The driver output leakage remains less than 1µA, even if the transmitter output is backdriven between 0V and (V CC + 6V). Below -0.5V, the transmitter is diode clamped to ground with 1k Ωseries impedance. The transmitter is also zener clamped to approximately V CC + 6V, with a series impedance of 1k Ω.The driver output slew rate is limited to less than 30V/µs as required by the EIA/TIA-232E and V.28 specifica-tions. Typical slew rates are 24V/µs unloaded and 10V/µs loaded with 3Ωand 2500pF.RS-232 ReceiversEIA/TIA-232E and V.28 specifications define a voltage level greater than 3V as a logic 0, so all receivers invert.Input thresholds are set at 0.8V and 2.4V, so receivers respond to TTL level inputs as well as EIA/TIA-232E and V.28 levels.The receiver inputs withstand an input overvoltage up to ±25V and provide input terminating resistors withDrivers/ReceiversTable 2. Three-State Control of ReceiversMAX220–MAX249Drivers/Receiversnominal 5k Ωvalues. The receivers implement Type 1interpretation of the fault conditions of V.28 and EIA/TIA-232E.The receiver input hysteresis is typically 0.5V with a guaranteed minimum of 0.2V. This produces clear out-put transitions with slow-moving input signals, even with moderate amounts of noise and ringing. The receiver propagation delay is typically 600ns and is independent of input swing direction.Low-Power Receive ModeThe low-power receive mode feature of the MAX223,MAX242, and MAX245–MAX249 puts the IC into shut-down mode but still allows it to receive information. This is important for applications where systems are periodi-cally awakened to look for activity. Using low-power receive mode, the system can still receive a signal that will activate it on command and prepare it for communi-cation at faster data rates. This operation conserves system power.Negative Threshold—MAX243The MAX243 is pin compatible with the MAX232A, differ-ing only in that RS-232 cable fault protection is removed on one of the two receiver inputs. This means that control lines such as CTS and RTS can either be driven or left floating without interrupting communication. Different cables are not needed to interface with different pieces of equipment.The input threshold of the receiver without cable fault protection is -0.8V rather than +1.4V. Its output goes positive only if the input is connected to a control line that is actively driven negative. If not driven, it defaults to the 0 or “OK to send” state. Normally‚ the MAX243’s other receiver (+1.4V threshold) is used for the data line (TD or RD)‚ while the negative threshold receiver is con-nected to the control line (DTR‚ DTS‚ CTS‚ RTS, etc.). Other members of the RS-232 family implement the optional cable fault protection as specified by EIA/TIA-232E specifications. This means a receiver output goes high whenever its input is driven negative‚ left floating‚or shorted to ground. The high output tells the serial communications IC to stop sending data. To avoid this‚the control lines must either be driven or connected with jumpers to an appropriate positive voltage level.Shutdown—MAX222–MAX242On the MAX222‚ MAX235‚ MAX236‚ MAX240‚ and MAX241‚ all receivers are disabled during shutdown.On the MAX223 and MAX242‚ two receivers continue to operate in a reduced power mode when the chip is in shutdown. Under these conditions‚ the propagation delay increases to about 2.5µs for a high-to-low input transition. When in shutdown, the receiver acts as a CMOS inverter with no hysteresis. The MAX223 and MAX242 also have a receiver output enable input (EN for the MAX242 and EN for the MAX223) that allows receiver output control independent of SHDN (SHDN for MAX241). With all other devices‚ SHDN (SH DN for MAX241) also disables the receiver outputs.The MAX225 provides five transmitters and five receivers‚ while the MAX245 provides ten receivers and eight transmitters. Both devices have separate receiver and transmitter-enable controls. The charge pumps turn off and the devices shut down when a logic high is applied to the ENT input. In this state, the supply cur-rent drops to less than 25µA and the receivers continue to operate in a low-power receive mode. Driver outputs enter a high-impedance state (three-state mode). On the MAX225‚ all five receivers are controlled by the ENR input. On the MAX245‚ eight of the receiver out-puts are controlled by the ENR input‚ while the remain-ing two receivers (RA5 and RB5) are always active.RA1–RA4 and RB1–RB4 are put in a three-state mode when ENR is a logic high.Receiver and Transmitter EnableControl InputsThe MAX225 and MAX245–MAX249 feature transmitter and receiver enable controls.The receivers have three modes of operation: full-speed receive (normal active)‚ three-state (disabled)‚ and low-power receive (enabled receivers continue to function at lower data rates). The receiver enable inputs control the full-speed receive and three-state modes. The transmitters have two modes of operation: full-speed transmit (normal active) and three-state (disabled). The transmitter enable inputs also control the shutdown mode. The device enters shutdown mode when all transmitters are disabled. Enabled receivers function in the low-power receive mode when in shutdown.M A X 220–M A X 249Tables 1a–1d define the control states. The MAX244has no control pins and is not included in these tables. The MAX246 has ten receivers and eight drivers with two control pins, each controlling one side of the device. A logic high at the A-side control input (ENA )causes the four A-side receivers and drivers to go into a three-state mode. Similarly, the B-side control input (ENB ) causes the four B-side drivers and receivers to go into a three-state mode. As in the MAX245, one A-side and one B-side receiver (RA5 and RB5) remain active at all times. The entire device is put into shut-down mode when both the A and B sides are disabled (ENA = ENB = +5V).The MAX247 provides nine receivers and eight drivers with four control pins. The ENRA and ENRB receiver enable inputs each control four receiver outputs. The ENTA and ENTB transmitter enable inputs each control four drivers. The ninth receiver (RB5) is always active.The device enters shutdown mode with a logic high on both ENTA and ENTB .The MAX248 provides eight receivers and eight drivers with four control pins. The ENRA and ENRB receiver enable inputs each control four receiver outputs. The ENTA and ENTB transmitter enable inputs control four drivers each. This part does not have an always-active receiver. The device enters shutdown mode and trans-mitters go into a three-state mode with a logic high on both ENTA and ENTB .The MAX249 provides ten receivers and six drivers with four control pins. The ENRA and ENRB receiver enable inputs each control five receiver outputs. The ENTA and ENTB transmitter enable inputs control three dri-vers each. There is no always-active receiver. The device enters shutdown mode and transmitters go into a three-state mode with a logic high on both ENTA and ENTB . In shutdown mode, active receivers operate in a low-power receive mode at data rates up to 20kb/s.__________Applications InformationFigures 5 through 25 show pin configurations and typi-cal operating circuits. In applications that are sensitive to power-supply noise, V CC should be decoupled to ground with a capacitor of the same value as C1 and C2 connected as close as possible to the device.Drivers/Receivers。

MEMORY存储芯片MAX7219CWG中文规格书
rupt, the host (Bus Master) interrogates the bus slave devices via a special receive-byte operation that includes the alert response address. The data returned by this receive-byte operation is the address of the offending slave device. The interrupt pointer address can activate several different slave devices simultane-ously. If more than one slave attempts to respond, bus arbitration rules apply, with the lowest address code going first. The other device(s) will not generate an acknowledge and will continue to hold the ALERT line low or repeat the START-STOP interrupt until serviced.Clearing Interrupts via Alert ResponseWhen a fault occurs, ALERT asserts and latches low. Ifthe fault is momentary and disappears before the device is serviced, ALERT remains asserted. Normally,the master sends out the Alert Response address fol-lowed by a read bit (00011001). ALERT clears whenthe device responds by successfully putting its address on the bus. Reading the Alert Response address is the only method for clearing hardwareand software interrupt latches.Clearing the interrupthas no effect on the state of the status registers.

I/O Read Timing DiagramM A X 1661/M A X 1662/M A X 1663START-STOP Software Interrupt The START-STOP interrupt is a method for the slave device to initiate a signal over the 2-wire interface with-out the need for a third (interrupt) wire. A START-STOP interrupt is a start condition followed by a stop condi-tion; in other words, SMBDATA goes low and then high with SMBCLK high (Figure 5 shows the START-STOP interrupt and a subsequent Alert Response transmis-sion used to clear the interrupt). The START-STOPfunction can be disabled (masked) by setting the dataregister mask SS (bit 6) high.In order to avoid bus collisions, the START-STOP inter-rupt will not occur when the bus is busy. If the devicebegins a start condition simultaneously with anothertransmitter on the bus, it recognizes the falling SMB-CLK as a collision and re-transmits the interrupt whenthe bus becomes available. Upon thermal shutdown ora transition on an I/O line, the device issues only oneSTART-STOP interrupt, and won’t repeat it unless therehas been a collision. However, thermal-shutdown faults,not being edge triggered, may result in a continuousstream of START-STOP bits.Input/Output PinsEach input/output (I/O) is protected by an internal20mA (typical) current-limit circuit. The I/O current limitdepends on the supply voltage and the voltage appliedto the I/O pins (see Typical Operating Characteristics ).The typical I/O bias current is 0.5µA to V I/O_= 28V.The ability of the I/Os to sink current depends on V CC as well as the voltage on the I/O. Typical pull-down on-resistance at V CC = 2.7V and 5.5V is 106Ωand 66Ω,respectively. I/O source and sink capability can affectthe rise and fall times of external power MOSFETs com-monly used in power-switching applications. Other fac-tors include the V GS , the input capacitance of the MOS-FET, and the pull-up resistor value used in the circuit.Typical MOSFET gate capacitance ranges from 150pF to 2000pF. Increasing the RC time constant slows down the MOSFET’s response, but provides for a smoother transition.Power-On Reset The power-on reset circuit keeps the external MOSFETs off during a power-up sequence. When the supply volt-age falls below the power-on reset threshold voltage,the MAX1662/MAX1663’s outputs reset to a high-impedance state, and the MAX1661’s outputs reset to a low state. During the initial power-up sequence, as V CC increases, the ALERT pin goes low and then high,which indicates the device is powered on. The time between the low and high state on ALERT is the power-on delay time. Below V CC = 0.8V (typical) the POR states can’t be enforced, and the I/O pins of all ver-sions exhibit increasingly weak pull-down current capa-bility, eventually becoming high impedance.Thermal Shutdown These devices have internal thermal-shutdown circuitry that turns off all output stages (I/O pins) when the junc-tion temperature exceeds +140°C typical. Thermal shutdown only occurs during an overload condition on the I/O pins. The device cycles between thermal shut-down and the overcurrent condition until the overload condition is removed. This could cause a sustained START-STOP interrupt and, in the extreme case, tie up the master controller. However, the device asserts ALERT low, indicating this fault status.Serial-to-Parallel/Parallel-to-Serial Converters and Load-Switch Controllers with SMBus InterfaceFigure 5.

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.
