MM74C373N数据手册集成电路（IC）的锁存器规格书PDF

描述 Description

General Description
The MM74C373 and MM74C374 are integrated, complementary MOS (CMOS), 8-bit storage elements with 3-STATE outputs. These outputs have been specially designed to drive high capacitive loads, such as one might find when driving a bus, and to have a fan out of 1 when
driving standard TTL. When a high logic level is applied to the OUTPUT DISABLE input, 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.

特性 Features

■Wide supply voltage range: 3V to 15V
■High noise immunity: 0.45 VCC(typ.)
■Low power consumption
■TTL compatibility:  Fan out of 1driving standard TTL
■Bus driving capability
■3-STATE outputs
■Eight storage elements in one package

简介

MM74C373N属于集成电路（IC）的锁存器。由制造生产的MM74C373N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。
