MC74VHCT138AD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

MC74VHCT138AD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MC74VHCT138AD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 MC74VHCT138A is an advanced high speed CMOS 3–to–8 decoder fabricated with silicon gate CMOS technology. It achieves high speed operation similar to equivalent Bipolar Schottky TTL while maintaining CMOS low power dissipation.
