SN74HCT125DT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

SN74HCT125DT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SN74HCT125DT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。

1 Features

2 Description

The SNx4HCT125 contains four independent buffers

with TTL-compatible inputs and 3-state outputs. Each

gate performs the Boolean function Y = A in positive

logic.
