DM74S151数据手册集成电路（IC）的信号开关多路复用器解码器规格书PDF

描述 Description

General Description
These data selectors/multiplexers contain full on-chip decoding to select the desired data source. The DM74S151 selects one-of-eight data sources. The DM74S151 has a strobe input which must be at a low logic level to enable these devices. A high level at the strobe forces the W output HIGH and the Y output LOW.
The DM74S151 features complementary W and Y outputs.

特性 Features

■ Select one-of-eight data lines
■ Performs parallel-to-serial conversion
■ Permits multiplexing from N lines to one line
■ Also for use as Boolean function generator
■ Typical average propagation delay time, data input to W output 4.5 ns
■ Typical power dissipation 225 mW 

简介

DM74S151属于集成电路（IC）的信号开关多路复用器解码器。由制造生产的DM74S151信号开关，多路复用器，解码器逻辑型信号开关、多路复用器和编码器 IC 可用于对以数字格式表示数据的电信号进行路由和选择。这些器件与设计用于模拟信号的类似产品有所不同，它们保留的信息表示为两个电状态之一，而不是两个外部界限内的无穷变化量。
