HCF4555BEY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

HCF4555BEY属于集成电路（IC）的信号开关多路复用器解码器。由意法半导体集团制造生产的HCF4555BEY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。

DESCRIPTION

The HCC4555B, HCC4556B (extended temperature range) and the HCF4555B, HCF4556B (intermediate temperature range) are monolithic integrated circuits available in 16-lead dual in-line plastic or ceramic package and plastic micropackage.

The HCC/HCF4555B and HCC/HCF4556B are dual one-of-four decoders/demultiplexers• Each decoder has two select inputs (A and B), an Enable input (E), and four mutually exclusive outputs• On the HCC/HCF4555B the outputs are high on select; on the HCC/HCF4556B the outputs are low on select• When the Enable input is high, the outputs of the HCC/HCF4555B remain low and the outputs of the HCC/HCF4556B remain high regardless of the state of the select inputs A and B.

4555B OUTPUTS HIGH ON SELECT

4556B OUTPUTS LOW ON SELECT
