MC74HC125ADT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

MC74HC125ADT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MC74HC125ADT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。

The MC74HC125A and MC74HC126A are identical in pinout to the LS125 and LS126. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs.

The HC125A and HC126A noninverting buffers are designed to be used with 3–state memory address drivers, clock drivers, and other bus–oriented systems. The devices have four separate output enables that are active–low (HC125A) or active–high (HC126A).
