SN74HC153NS集成电路（IC）的信号开关多路复用器解码器规格书PDF中文资料

SN74HC153NS属于集成电路（IC）的信号开关多路复用器解码器。由德州仪器制造生产的SN74HC153NS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。

2 Description

The SNx4HC153 is a dual data selector/multiplexer

containing full binary decoding to select one of

four data sources. Both channels are controlled by

the same address select inputs, and each channel

includes its own strobe (G) input. A high level at the

strobe terminal forces the repective output low.
