M74HC573B1R集成电路（IC）的锁存器规格书PDF中文资料

M74HC573B1R属于集成电路（IC）的锁存器。由意法半导体集团制造生产的M74HC573B1R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。

DESCRIPTION

The M74HC573 is an high speed CMOS OCTAL LATCH WITH 3-STATE OUTPUTS fabricated with silicon gate C2MOS technology

■ HIGH SPEED: tPD = 13ns (TYP.) at VCC = 6V
