SN74AHCT125 具有三态输出的四路总线缓冲器闸

SN74AHCT125 描述

The ’AHCT125 devices are quadruple bus buffer gates 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
