SN74LVCH162244AVR集成电路（IC）的缓冲器驱动器接收器收发器规格书PDF中文资料

SN74LVCH162244AVR属于集成电路（IC）的缓冲器驱动器接收器收发器。由美国德州仪器公司制造生产的SN74LVCH162244AVR缓冲器，驱动器，接收器，收发器逻辑缓冲器、驱动器、接收器和收发器允许隔离对某个电路的逻辑信号的访问，以用于另一电路。缓冲器将其输入信号（不变或反相）传递到其输出，并可能用于清除弱信号或驱动负载。在布尔逻辑仿真器中，缓冲器主要用于增加传播延迟。逻辑接收器和收发器允许在数据总线之间进行隔离通信。

3 Description

This 16-bit buffer/driver is designed for 1.65-V to

3.6-V VCC operation.

The device can be used as four 4-bit buffers, two

8-bit buffers, or one 16-bit buffer.

The SN74LVCH162244A device is designed

specifically to improve both the performance and

density of 3-state memory address drivers, clock

drivers, and bus-oriented receivers and transmitters.
