MC14028BF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

MC14028BF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MC14028BF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 MC14028B decoder is constructed so that an 8421 BCD code on the four inputs provides a decimal (one−of−ten) decoded output, while a 3−bit binary input provides a decoded octal (one−of−eight) code output with D forced to a logic “0”. Expanded decoding such as binary−to−hexadecimal (one−of−sixteen), etc., can be achieved by using other MC14028B devices. The part is useful for code conversion, address decoding, memory selection control, demultiplexing, or readout decoding.
