移位寄存器74HC164中文资料(功能,真值表,引脚图及电气参数介绍)
SN54HC164,/SN74HC164是8位移位寄存器，当其中一个（或二个）选通串行输入端的低电平禁止进入新数据，并把第一个触发器在下一个时钟脉冲来后复位到低电平时，门控串行输入端（A 和B）可完全控制输入数据。

一个高电平输入后就使另一个输入端赋能，这个输入就决定了第一个触发器的状态。

虽然不管时钟处于高电平或低电平时，串行输入端的数据都可以被改变，但只有满足建立条件的信息才能被输入。

时钟控制发生在时钟输入由低电平到高电平的跃变上。

为了减小传输线效应，所有输入端均采用二极管钳位。

HD74HC640/HD74HC643
Octal Bus Transceivers (with 3-state outputs)
Description
Each device has an active enable G and a direction control input, DIR. when DIR is high, data flows from the A inputs to the B outputs. When DIR is low, data flows from the B inputs to the A outputs. The HD74HC640 transfers inverted data from one bus to other and the HD74HC643 transfers inverted data from the A bus to the B bus and true data from the B bus to the A bus.
Features
• High Speed Operation: tpd = 12 ns typ (CL = 50 pF) • High Output Current: Fanout of 15 LSTTL Loads • Wide Operating Voltage: VCC = 2 to 6 V • Low Input Current: 1 µA max • Low Quiescent Supply Current: ICC (static) = 4 µA max (Ta = 25°C)

74系列逻辑器件命名规格

74系列逻辑器件命名规格一、引言74系列逻辑器件是一类广泛应用于数字电路中的集成电路芯片，由美国德州仪器公司（Texas Instruments）研发和生产。

这些芯片具有高速、低功耗和稳定可靠的特点，被广泛应用于计算机、通信设备、工业控制等领域。

为了方便用户选择和使用不同功能的逻辑器件，德州仪器公司为每种芯片定义了一套规范的命名规格。

本文将详细介绍74系列逻辑器件的命名规格，包括前缀、功能码和后缀等内容。

二、命名规格1. 前缀74系列逻辑器件的命名以“SN”作为前缀，表示“德州仪器（Texas Instruments）”的英文缩写。

例如，SN74LS00是一种常见的74系列逻辑门芯片。

2. 功能码每种逻辑器件根据其功能被分配了一个唯一的功能码。

这个功能码在芯片型号中起到了区分不同类型芯片的作用。

功能码通常由两个字母和两位数字组成：•第一个字母表示芯片类型：–S：逻辑门（Logic Gates）–N：触发器（Flip-Flops）–D：锁存器（Latches）–T：计数器（Counters）–etc.•第二个字母表示芯片家族：–L：低功耗系列（Low-power Schottky）–H：高速系列（High-speed）•数字部分表示具体功能和特性，如门数量、输入/输出端口数等。

举例说明：•SN74LS00：SN代表德州仪器公司，74代表逻辑器件系列，LS代表低功耗系列，00表示具体的逻辑门芯片。

•SN74HC595：SN代表德州仪器公司，74代表逻辑器件系列，HC代表高速系列，595表示具体的移位寄存器芯片。

3. 后缀根据不同芯片的功能和特性，后缀部分用于进一步描述逻辑器件的规格。

常见的后缀有：•A/B/C/D/E/F/G/H/I/J/K/L/M/N/P/Q/R/S/T/U/V/W/X/Y/Z等：用于区分不同尺寸或包装形式的芯片。

•N/R/S/T等：表示不同温度范围的工作级别。

•E/F等：表示不同电源电压级别。
