HCF4042BEY屬于集成電路（IC）的鎖存器。由意法半導體集團制造生產的HCF4042BEY鎖存器鎖存器是類似于觸發(fā)器的基本數字存儲設備，但是不同之處在于，在鎖存使能（或類似命名）信號處于有效邏輯狀態(tài)的任何時間，保持的邏輯狀態(tài)都可以改變。“透明”鎖存器還允許設備輸出在鎖存使能信號有效時反映輸入的當前狀態(tài)，而相反的是，狀態(tài)僅在保持狀態(tài)已固定時改變。

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.
