SN74AHCT125QPWREP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

SN74AHCT125QPWREP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SN74AHCT125QPWREP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

The SN74AHCT125 is a quadruple bus buffer gate featuring independent line drivers with 3-state outputs. Each

output is disabled when the associated output-enable (OE) input is high. When OE is low, the respective gate

passes the data from the A input to its Y output.

To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup

resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
