MC74LCX573集成电路（IC）的锁存器规格书PDF中文资料

MC74LCX573属于集成电路（IC）的锁存器。由安森美半导体制造生产的MC74LCX573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。

Low-Voltage CMOS Octal Transparent Latch Flow Through Pinout

With 5 V−Tolerant Inputs and Outputs (3−State, Non−Inverting)

The MC74LCX573 is a high performance, non−inverting octal transparent latch operating from a 2.3 to 3.6 V supply. High impedance TTL compatible inputs significantly reduce current loading to input drivers while TTL compatible outputs offer improved switching noise performance. A VIspecification of 5.5 V allows MC74LCX573 inputs to be safely driven from 5.0 V devices.
