CD74HC373M96集成电路（IC）的锁存器规格书PDF中文资料

CD74HC373M96属于集成电路（IC）的锁存器。由德州仪器制造生产的CD74HC373M96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。

1 Features

• 2-V to 6-V VCC operation

• Wide operating temperature range of

–55℃ to 125℃

• Balanced propagation delays and transition times

• Standard outputs drive up to 15 LS-TTL loads

• Significant power reduction compared to LS-TTL

Logic ICs

2 Description

The ’HC373 devices are octal transparent D-type

latches designed for 2-V to 6-V VCC operation.

When the latch-enable (LE) input is high, the Q

outputs follow the data (D) inputs. When LE is low,

the Q outputs are latched at the logic levels of the D

inputs.
