The device is byte controlled. The flip-flops appear transparent to the data when the Latch Enable (LE) is HIGH. When LE is LOW, the data that meets the setup time is latched. Data appears on the bus when the Output Enable (OE) is LOW. When OE is HIGH, the outputs are in a high impedance state.The LVTH16373 data inputs include bushold, eliminating the need for external pull-up resistors to hold unused inputs.These latches are designed for low-voltage (3.3V) V CC applications, but with the capability to provide a TTL inter-face to a 5V environment. The LVT16373 and LVTH16373are fabricated with an advanced BiCMOS technology to achieve high speed operation similar to 5V ABT while maintaining a low power dissipation.Featuress Input and output interface capability to systems at 5V V CC s Bushold data inputs eliminate the need for external pull-up resistors to hold unused inputs (74LVTH16373),also available without bushold feature (74LVT16373)s Live insertion/extraction permitteds Power Up/Power Down high impedance provides glitch-free bus loading s Outputs source/sink 32 mA/ 64 mAs Functionally compatible with the 74 series 16373s Latch-up performance exceeds 500 mA s ESD performance:Human-body model ! 2000V Machine model ! 200V Charged-device model ! 1000Vs Also packaged in plastic Fine-Pitch Ball Grid Array (FBGA) (Preliminary)Ordering Code:Note 1: BGA package available in Tape and Reel only.Note 2: Device also available in Tape and Reel.

The device is byte controlled with each byte functioning identically, but inde-pendent of the other. Control pins can be shorted together to obtain full 16-bit operation. The following description applies to each byte. When the Latch Enable (LE n ) input is HIGH, data on the D n enters the latches. In this condition the latches are transparent, i.e, a latch output will change states each time its D input changes. When LE n is LOW,the latches store information that was present on the D inputs a setup time preceding the HIGH-to-LOW transition of LE n . The 3-STATE standard outputs are controlled by the Output Enable (OE n ) input. When OE n is LOW, the standard outputs are in the 2-state mode. When OE n is HIGH, the standard outputs are in the high impedance mode but this does not interfere with entering new data into the latches.Logic DiagramsPlease note that these diagrams are provided only for the understanding of logic operations and should not be used to estimate propagation delays. 474L V T 16373 • 74L V T H 16373Absolute Maximum Ratings (Note 3)Recommended Operating ConditionsNote 3: Absolute Maximum continuous ratings are those values beyond which damage to the device may occur.

The following is a brief description of the setup used to measure the noise characteristics of FACT.Equipment:Hewlett Packard Model 8180A Word Generator PC-163A Test FixtureTektronics Model 7854 OscilloscopeProcedure:1.Verify Test Fixture Loading: Standard Load 50 pF,500:.2.Deskew the HFS generator so that no two channelshave greater than 150 ps skew between them. This requires that the oscilloscope be deskewed first. It is important to deskew the word generator channels before testing. This will ensure that the outputs switch simultaneously.3.Terminate all inputs and outputs to ensure proper load-ing of the outputs and that the input levels are at the correct voltage.4.Set the HFS generator to toggle all but one output at afrequency of 1 MHz. Greater frequencies will increase DUT heating and effect the results of the measure-ment.5.Set the HFS generator input levels at 0V LOW and 3VHIGH for ACT devices and 0V LOW and 5V HIGH for AC devices. Verify levels with an oscilloscopeNote 9: V OHV and V OLP are measured with respect to ground reference.Note 10: Input pulses have the following characteristics: f 1 MHz, t r 3ns,t f 3 ns, skew 150 ps.FIGURE 1. Quiet Output Noise Voltage WaveformsV OLP /V OLV and V OHP /V OHV :•Determine the quiet output pin that demonstrates the greatest noise levels. The worst case pin will usually be the furthest from the ground pin. Monitor the output volt-ages using a 50: coaxial cable plugged into a standard SMB type connector on the test fixture. Do not use an active FET probe.•Measure V OLP and V OLV on the quiet output during the worst case transition for active and enable. Measure V OHP and V OHV on the quiet output during the worst case active and enable transition.•Verify that the GND reference recorded on the oscillo-scope has not drifted to ensure the accuracy and repeat-ability of the measurements.V ILD and V IHD :•Monitor one of the switching outputs using a 50: coaxial cable plugged into a standard SMB type connector on the test fixture. Do not use an active FET probe.•First increase the input LOW voltage level, V IL , until the output begins to oscillate or steps out a min of 2 ns.Oscillation is defined as noise on the output LOW level that exceeds V IL limits, or on output HIGH levels that exceed V IH limits. The input LOW voltage level at which oscillation occurs is defined as V ILD .•Next decrease the input HIGH voltage level.V IH until the output begins to oscillate or steps out a mine of 2 ns.Oscillation is defined as noise on the output LOW level that exceeds V IL limits, or on output HIGH levels that exceed V IH limits.

All flip-flop outputs are brought out through 3-STATE buffers to separate I/O pins that also serve as data inputs in the parallel load mode. Q 0 and Q 7are also brought out on other pins for expansion in serial shifting of longer words.A LOW signal on SR overrides the Select inputs and allows the flip-flops to be reset by the next rising edge of CP . Allother state changes are also initiated by the LOW-to-HIGH CP transition. Inputs can change when the clock is in either state provided only that the recommended setup and hold times, relative to the rising edge of CP , are observed.A HIGH signal on either OE 1 or OE 2 disables the 3-ST ATE buffers and puts the I/O pins in the high impedance state.In this condition the shift, load, hold and reset operations can still occur.

74AC253 • 74ACT253
Functional Description
The AC/ACT253 contains two identical 4-input multiplexers with 3-STATE outputs. They select two bits from four sources selected by common Select inputs (S0, S1). The 4input multiplexers have individual Output Enable (OEa, OEb) inputs which, when HIGH, force the outputs to a high impedance (High Z) state. This device is the logic implementation of a 2-pole, 4-position switch, where the position of the switch is determined by the logic levels supplied to the two select inputs. The logic equations for the outputs are shown: Za = OEa • Zb = OEb • (I0a • S1 • S0 + I1a • S1 • S0 + I2a • S1 • S0 + I3a • S1 • S0) (I0b • S1 • S0 + I1b • S1 • S0 + I2b • S1 • S0 + I3b • S1 • S0) If the outputs of 3-STATE devices are tied together, all but one device must be in the high impedance state to avoid high currents that would exceed the maximum ratings. Designers should ensure that Output Enable signals to 3STATE devices whose outputs are tied together are designed so that there is no overlap.

LED驱动控制专用芯片TM1637介绍

LED驱动控制专用芯片TM1637介绍特性描述TM1637是一种带键盘扫描接口的LED（发光二极管显示器）驱动控制专用电路，内部集成有MCU 数字接口、数据锁存器、LED 高压驱动、键盘扫描等电路。

功能特点显示模式（8 段×6 位）,支持共阳数码管输出键扫描（8×2bit），增强型抗干扰按键识别电路辉度调节电路（占空比 8 级可调）两线串行接口（CLK，DIO）振荡方式：内置RC 振荡（450KHz+5%）封装形式：DIP20/SOP20管脚信息管脚功能读键扫数据键扫矩阵为8×2bit，如下所示：在有按键按下时，读键数据如下：注意：在无按键按下时，读键数据为：1111_1111，低位在前，高位在后。

显示寄存器地址和显示模式该寄存器存储通过串行接口从外部器件传送到TM1637 的数据，地址00H-05H共6个字节单元，分别与芯片SGE和GRID管脚所接的LED 灯对应，分配如下图：写LED显示数据的时候，按照从显示地址从低位到高位，从数据字节的低位到高位操作。

接口说明微处理器的数据通过两线总线接口和TM1637 通信，在输入数据时当CLK 是高电平时，DIO 上的信号必须保持不变；只有CLK 上的时钟信号为低电平时，DIO 上的信号才能改变。

数据输入的开始条件是CLK为高电平时，DIO 由高变低；结束条件是CLK 为高时，DIO 由低电平变为高电平。

TM1637 的数据传输带有应答信号ACK，当传输数据正确时，会在第八个时钟的下降沿，芯片内部会产生一个应答信号ACK 将DIO 管脚拉低，在第九个时钟结束之后释放DIO 口线。

1、指令数据传输过程如下图（读按键数据时序）Command ：读按键指令；S0、S1、S2、K1、K2 组成按键信息编码，S0、S1、S2 为SGn 的编码，K1、K2 为K1 和K2 键的编码，读按键时，时钟频率应小于250K ，先读低位，后读高位。

器件的输入是和标准CMOS输出兼容的；加上拉电阻，他们能和LS/ALSTTL输出兼容。

当锁存使能端为高时，这些器件的锁存对于数据是透明的（也就是说输出同步）。

当锁存使能变低时，符合建立时间和保持时间的数据会被锁存。

×输出能直接接到CMOS，NMOS和TTL接口上×操作电压范围：2.0V~6.0V×低输入电流：1.0uA×CMOS器件的高噪声抵抗特性·三态总线驱动输出·置数全并行存取·缓冲控制输入·使能输入有改善抗扰度的滞后作用原理说明：M54HC563/74HC563/M54HC573/74HC573的八个锁存器都是透明的D 型锁存器，当使能（G）为高时，Q 输出将随数据（D）输入而变。

当使能为低时，输出将锁存在已建立的数据电平上。

输出控制不影响锁存器的内部工作，即老数据可以保持，甚至当输出被关闭时，新的数据也可以置入。

这种电路可以驱动大电容或低阻抗负载，可以直接与系统总线接口并驱动总线，而不需要外接口。

特别适用于缓冲寄存器，I/O 通道，双向总线驱动器和工作寄存器。

© 2005 Fairchild Semiconductor Corporation DS012002February 1994Revised May 200574LCX16373 Low Voltage 16-Bit Transparent Latch with 5V Tolerant Inputs and Outputs74LCX16373Low Voltage 16-Bit Transparent Latch with 5V Tolerant Inputs and OutputsGeneral DescriptionThe LCX16373 contains sixteen non-inverting latches with 3-STATE outputs and is intended for bus oriented applica-tions. The device is byte controlled. The flip-flops appear transparent to the data when the Latch Enable (LE) is HIGH. When LE is LOW, the data that meets the setup time is latched.

The device is byte controlled with each byte functioning identically, but independent of the other. Control pins can be shorted together to obtain full 16-bit operation. The following description applies to each byte. When the Latch Enable (LE n ) input is HIGH, data on the I n enters the latches. In this condition the latches are transparent, i.e. a latch output will change state each timeits I input changes. When LE n is LOW, the latches store information that was present on the I inputs a setup time preceding the HIGH-to-LOW transition of LE n . The 3-STATE standard outputs are controlled by the Output Enable (OE n ) input. When OE n is LOW, the standard out-puts are in the 2-state mode. When OE n is HIGH, the stan-dard outputs are in the high impedance mode but this does not interfere with entering new data into the latches.Logic DiagramsPlease note that this diagram is provided only for the understanding of logic operations and should not be used to estimate propagation delays. 474L C X 16373Absolute Maximum Ratings (Note 4)Recommended Operating Conditions (Note 6)Note 4: The Absolute Maximum Ratings are those values beyond which the safety of the device cannot be guaranteed.

HD74LVC16373A16-bit D-type Transparent Latches with 3-state OutputsADE-205-121B(Z)3rd EditionDecember 1996 DescriptionThe HD74LVC16373A has sixteen D type latches with three state outputs in a 48 pin package. When the latch enable input is high, the Q outputs will follow the D inputs. When the latch enable goes low, data at the D inputs will be retained at the outputs until latch enable returns high again. When a high logic level is applied to the output control input (1G, 2G), all outputs go to a high impedance state, regardless of what signals are present at the other inputs and the state of the storage elements. Low voltage and high speed operation is suitable at the battery drive product (note type personal computer) and low power consumption extends the life of a battery for long time operation.Features• V CC = 2.0 V to 5.5 V• All inputs V IH (Max.) = 5.5 V (@V CC = 0 V to 5.5 V)• All outputs V OUT (Max.) = 5.5 V (@V CC = 0 V or output off state)• Typical V OL ground bounce < 0.8 V (@V CC = 3.3 V, Ta = 25°C)• Typical V OH undershoot > 2.0 V (@V CC = 3.3 V, Ta = 25°C)• High output current ±24 mA (@V CC = 3.0 V to 5.5 V)Function TableInputsG LE D Output QH X X ZL H L LL H H HL L X QlevelH: HighL:Low levelX:ImmaterialZ:High impedanceQ:Level of Q before the indicated steady input conditions were established.HD74LVC16373A Pin Arrangement2HD74LVC16373A3Absolute Maximum RatingsItemSymbol Ratings Unit ConditionsSupply voltage V CC –0.5 to 6.0V Input diode current I IK –50mA V I = –0.5 V Input voltage V I –0.5 to 6.0V Output diode current I OK –50mA V O = –0.5 V 50mA V O = V CC +0.5 V Output voltage V O –0.5 to V CC +0.5V Output "H" or "L"–0.5 to 6.0V Output "Z" or V CC :OFF Output current I O±50mA V CC , GND current / pin I CC or I GND 100mA Storage temperatureTstg–65 to +150°CNote:The absolute maximum ratings are values which must not individually be exceeded, and furthermore,no two of which may be realized at the same time.Recommended Operating ConditonsItemSymbol Ratings Unit Conditions Supply voltage V CC 1.5 to 5.5V Data hold 2.0 to 5.5V At operation Input / output voltageV I 0 to 5.5V G , LE, D V O0 to V CC V Output "H" or "L"0 to 5.5V Output "Z" or V CC :OFFOperating temperature Ta –40 to 85°C Output currentI OH –12mA V CC = 2.7 V –24*2mA V CC = 3.0 V to 5.5 V I OL12mA V CC = 2.7 V 24*2mA V CC = 3.0 V to 5.5 V Input rise / fall time *1t r , t f10ns/VNotes: 1.This item guarantees maximum limit when one input switches.Waveform : Refer to test circuit of switching characteristics.2.duty cycle ≤ 50%HD74LVC16373A4Electrical CharacteristicsTa = –40 to 85°CItem Symbol V CC (V)Min Max Unit Test Conditions Input voltageV IH 2.7 to 3.6 2.0—V 4.5 to 5.5V CC ×0.7—V V IL2.7 to3.6—0.8V4.5 to5.5—V CC ×0.3V Output voltageV OH2.7 to 5.5V CC –0.2—V I OH = –100 µA 2.7 2.2—V I OH = –12 mA3.0 2.4—V 3.0 2.2—V I OH = –24 mA4.53.8—V V OL2.7 to 5.5—0.2V I OL = 100 µA 2.7—0.4V I OL = 12 mA3.0—0.55V I OL = 24 mA4.5—0.55V Input currentI IN 0 to 5.5—±5.0µA V IN = 5.5 V or GND Off state output current I OZ 2.7 to 5.5—±5.0µA V IN = V CC , GNDV OUT = 5.5 V or GND Output leak currentI OFF0—20µA V IN / V OUT = 5.5 V Quiescent supply current I CC2.7 to3.6—±20µA V IN / V OUT = 3.6 to 5.5 V 2.7 to 5.5—20µA V IN = V CC or GND∆I CC3.0 to 3.6—500µAV IN = one input at(V CC –0.6)V,other inputs at V CC or GNDHD74LVC16373A5Switching CharacteristicsTa = –40 to 85°CItemSymbol V CC (V)Min Typ Max Unit From (Input)To (Output)Propagation delay timet PLH 2.7——7.7ns DQt PHL 3.3±0.3 1.5—7.0ns 5.0±0.5—— 5.5ns t PLH 2.7——8.0ns LEQt PHL3.3±0.3 2.0—7.0ns 5.0±0.5—— 5.5ns Output enable timet ZH 2.7——8.0ns GQt ZL3.3±0.3 1.5—7.0ns 5.0±0.5—— 6.0ns Output disable timet HZ 2.7——8.0ns GQt LZ3.3±0.3 1.5—7.0ns 5.0±0.5—— 6.0ns Setup timet su2.7 2.0——ns3.3±0.3 2.0——ns 5.0±0.52.0——ns Hold timet h2.7 1.5——ns3.3±0.3 1.5——ns 5.0±0.51.5——ns Pulse widtht w2.73.0——ns 3.3±0.3 3.0——ns 5.0±0.53.0——ns Between output pins skew *1t OSLH 2.7———ns t OSHL3.3±0.3—— 1.0ns 5.0±0.5—— 1.0ns Input capacitance C IN 2.7— 3.0—pF Output capacitance C O2.7—15.0—pFNote:1.This parameter is characterized but not tested.tos LH = | t PLHm – t PLHn |, tos HL = | t PHLm – t PHLn |HD74LVC16373A Test CircuitWaveforms – 16HD74LVC16373A Waveforms – 2Waveforms – 37HD74LVC16373A Waveforms – 48Hitachi CodeJEDECEIAJWeight (reference value)TTP-48DB——0.20 gUnit: mm*Dimension including the plating thickness Base material dimensionCautions1.Hitachi neither warrants nor grants licenses of any rights of Hitachi’s or any third party’s patent,copyright, trademark, or other intellectual property rights for information contained in this document.Hitachi bears no responsibility for problems that may arise with third party’s rights, includingintellectual property rights, in connection with use of the information contained in this document.2.Products and product specifications may be subject to change without notice.
