3 Description

The SN74AHCT126-Q1 device 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 low. When OE

is high, 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 GND through a

pulldown resistor; the minimum value of the resistor

is determined by the current-sourcing capability of the

driver.
