MC74LVX139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

The MC74LVX139 is an advanced high speed CMOS 2-to-4 decoder/ demultiplexer fabricated with silicon gate CMOS technology.When the device is enabled (Ebar=low), it can be used for gating or as a data input for demultiplexing operations. When the enable input is held high, all four outputs are fixed high, independent of other inputs.The inputs tolerate voltages up to 7 V, allowing the interface of 5 V systems to 3 V systems.

简介

MC74LVX139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MC74LVX139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。
