3 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.
