CD74HCT153MT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

CD74HCT153MT属于集成电路（IC）的信号开关多路复用器解码器。由美国德州仪器公司制造生产的CD74HCT153MT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。

Description

The ’HC153 and ’HCT153 are dual 4- to 1-line

selector/multiplexers that select one of four sources for each

section by the common select inputs, S0 and S1. When the

enable inputs (1E, 2E) are HIGH, the outputs are in the LOW

state.
