74ALVCH162373中文资料Low Voltage 16-Bit Transparent Latch with Bushold and 26Ω Series Resistors in Outputs数据手册ONSEMI规格书

描述 Description

General Description
The ALVCH162373 contains sixteen non-inverting latches with 3-STATE outputs and is intended for bus oriented applications. The device is byte controlled. The flip-flops appear to be 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.

特性 Features

简介

74ALVCH162373属于集成电路（IC）的锁存器。由制造生产的74ALVCH162373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。
