MC74HC245ADTR2G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

MC74HC245ADTR2G属于集成电路（IC）的缓冲器驱动器接收器收发器。由安森美半导体制造生产的MC74HC245ADTR2G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。

Octal 3−State Noninverting Bus Transceiver

High−Performance Silicon−Gate CMOS

The MC74HC245A is identical in pinout to the LS245. The device inputs are compatible with standard CMOS outputs; with pull−up resistors, they are compatible with LSTTL outputs. The HC245A is a 3−state noninverting transceiver that is used for 2−way asynchronous communication between data buses. The device has an active−low Output Enable pin, which is used to place the I/O ports into high−impedance states. The Direction control determines whether data flows from A to B or from B to A.
