HCF4042B集成电路（IC）的锁存器规格书PDF中文资料

HCF4042B属于集成电路（IC）的锁存器。由意法半导体集团制造生产的HCF4042B锁存器锁存器是类似于触发器的基本数字存储设备，但是不同之处在于，在锁存使能（或类似命名）信号处于有效逻辑状态的任何时间，保持的逻辑状态都可以改变。“透明”锁存器还允许设备输出在锁存使能信号有效时反映输入的当前状态，而相反的是，状态仅在保持状态已固定时改变。

描述 Description

The HCC4000B series is composed of close to 80 monolithic types built with Metal Oxide Complementary technology. It provides Designers with high voltage noise tolerant complete Logic

series. It radiation hardness and immunity to Heavy Ions make this series to be usable in the

most difficult environmental conditions.
