MC14043BDR2集成电路（IC）的锁存器规格书PDF中文资料

MC14043BDR2属于集成电路（IC）的锁存器。由安森美半导体制造生产的MC14043BDR2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。

The MC14043B and MC14044B quad R−S latches are constructed with MOS P−Channel and N−Channel enhancement mode devices in a single monolithic structure. Each latch has an independent Q output and set and reset inputs. The Q outputs are gated through three−state buffers having a common enable input. The outputs are enabled with a logical “1” or high on the enable input; a logical “0” or low disconnects the latch from the Q outputs, resulting in an open circuit at the Q outputs.
