MC74LCX157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

MC74LCX157属于集成电路（IC）的信号开关多路复用器解码器。由安森美半导体制造生产的MC74LCX157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。

The MC74LCX157 is a high performance, quad 2−input multiplexer operating from a 2.3 to 3.6 V supply. High impedance TTL compatible inputs significantly reduce current loading to input drivers while TTL compatible outputs offer improved switching noise performance. A VI specification of 5.5 V allows MC74LCX157 inputs to be safely driven from 5 V devices.
