SN74LVC1G373集成电路（IC）的锁存器规格书PDF中文资料

SN74LVC1G373属于集成电路（IC）的锁存器。由德州仪器制造生产的SN74LVC1G373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。

3 Description

The SN74LVC1G373 device is a single D-type latch

designed for 1.65-V to 5.5-V VCC operation.

This device is particularly suitable for implementing

buffer registers, I/O ports, bidirectional bus drivers,

and working registers. While the latch-enable (LE)

input is high, the Q outputs follow the data (D) inputs.

When LE is taken low, the Q outputs are latched at

the logic levels set up at the D inputs.

NanoFree™ package technology is a major

breakthrough in IC packaging concepts, using the die

as the package.

OE does not affect the internal operations of the

latch. Old data can be retained or new data can be

entered while the outputs are in the high-impedance

state.
