SN74LVTH162373DL集成电路（IC）的锁存器规格书PDF中文资料

SN74LVTH162373DL属于集成电路（IC）的锁存器。由美国德州仪器公司制造生产的SN74LVTH162373DL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。

DESCRIPTION/ORDERING INFORMATION

The 'LVTH162373 devices are16-bit transparent D-type latches with 3-state outputs designed for low-voltage

(3.3-V) VCC operation, but with the capability to provide a TTL interface to a 5-V system environment. These

devices are particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and

working registers.
