MC74LVX573MEL集成电路（IC）的锁存器规格书PDF中文资料

MC74LVX573MEL属于集成电路（IC）的锁存器。由安森美半导体制造生产的MC74LVX573MEL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 MC74LVX573 is an advanced high speed CMOS octal latch with 3−state outputs. The inputs tolerate voltages up to 7.0 V, allowing the interface of 5.0 V systems to 3.0 V systems.

This 8−bit D−type latch is controlled by a latch enable input and an output enable input. When the output enable input is high, the eight outputs are in a high impedance state.
