3 Description

The SN74AHC125-Q1 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 put the device in the high-impedance state during power up or power down, tie OE to VCC through a pullup resistor; the current-sinking capability of the driver determines the minimum value of the resistor.
