MC14556BCP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

MC14556BCP属于集成电路（IC）的信号开关多路复用器解码器。由安森美半导体公司制造生产的MC14556BCP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。

Dual Binary to 1−of−4 Decoder/Demultiplexer

The MC14555B and MC14556B are constructed with complementary MOS (CMOS) enhancement mode devices. Each Decoder/Demultiplexer has two select inputs (A and B), an active low Enable input (E), and four mutually exclusive outputs (Q0, Q1, Q2, Q3). The MC14555B has the selected output go to the “high” state, and the MC14556B has the selected output go to the “low” state. Expanded decoding such as binary−to−hexadecimal (1−of−16), etc., can be achieved by using other MC14555B or MC14556B devices.
