MC74VHC157D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

MC74VHC157D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MC74VHC157D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 MC74VHC157 is an advanced high-speed CMOS quad 2-channel multiplexer, fabricated with silicon gate CMOS technology. It achieves high-speed operation similar to equivalent Bipolar-Schottky TTL, while maintaining CMOS low-power dissipation.
