SN74AUP1G125数据手册集成电路（IC）的缓冲器驱动器接收器收发器规格书PDF

描述 Description

The SN74AUP1G125 bus buffer gate is a single line driver with a 3-state output. The output is disabled when the output-enable (OE) input is high. This device has the input-disable feature, which allows floating input signals.

To ensure the high-impedance state during power up or power down, OE must be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
