description/ordering information
The SN74AHC1G125 is a single bus buffer gate/line driver with 3-state output. The output is disabled when the
output-enable (OE) input is high. When OE is low, true data is passed from the A input to the Y output.
To ensure the high-impedance state during power up or power down, OE should be tied to V
CC
through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
