SN74LVCH16543ADLR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

SN74LVCH16543ADLR属于集成电路（IC）的缓冲器驱动器接收器收发器。由德州仪器制造生产的SN74LVCH16543ADLR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。

DESCRIPTION/ORDERING INFORMATION

This 16-bit registered transceiver is designed for

1.65-V to 3.6-V VCC operation.

The SN74LVCH16543A can be used as two 8-bit

transceivers or one 16-bit transceiver. Separate

latch-enable (LEAB or LEBA) and output-enable

(OEAB or OEBA) inputs are provided for each

register, to permit independent control in either

direction of data flow.
