74LCX841数据手册集成电路（IC）的锁存器规格书PDF

描述 Description

General Description
The LCX841 consists of ten latches with 3-STATE outputs for bus organized system applications. The device is designed for low voltage (2.5V or 3.3V) VCC applications with capability of interfacing to a 5V signal environment. The LCX841 is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining CMOS low power dissipation.

简介

74LCX841属于集成电路（IC）的锁存器。由制造生产的74LCX841锁存器锁存器是类似于触发器的基本数字存储设备，但是不同之处在于，在锁存使能（或类似命名）信号处于有效逻辑状态的任何时间，保持的逻辑状态都可以改变。“透明”锁存器还允许设备输出在锁存使能信号有效时反映输入的当前状态，而相反的是，状态仅在保持状态已固定时改变。
