MC74HC373A集成电路（IC）的锁存器规格书PDF中文资料

MC74HC373A属于集成电路（IC）的锁存器。由安森美半导体公司制造生产的MC74HC373A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。

Octal 3-State Non-Inverting Transparent Latch

High–Performance Silicon–Gate CMOS

The MC74HC373A is identical in pinout to the LS373. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs.

The HC373A is the non–inverting version of the HC533A.

• Output Drive Capability: 15 LSTTL Loads

• Outputs Directly Interface to CMOS, NMOS and TTL

• Operating Voltage Range: 2.0 to 6.0 V

• Low Input Current: 1.0 µA

• High Noise Immunity Characteristic of CMOS Devices

• In Compliance with the Requirements Defined by JEDEC Standard

No. 7A

• Chip Complexity: 186 FETs or 46.5 Equivalent Gates
