SN74HC42D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

SN74HC42D属于集成电路（IC）的信号开关多路复用器解码器。由德州仪器制造生产的SN74HC42D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。

Decoders

description/ordering information

These decimal decoders consist of eight inverters and ten 4-input NAND gates. The inverters are connected

in pairs to make BCD input data available for decoding by the NAND gates. Full decoding of valid input logic

ensures that all inputs remain off for all invalid input conditions.
