3 Description

The SNx4AHC125 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 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.
