3 Description

The SN74AHC126-Q1 devices are quadruple bus

buffer gates featuring independent line drivers with

3-state outputs.

For the high-impedance state during power up or

power down, OE can be tied to GND through a pulldown

resistor; the minimum value of the resistor is

determined by the current-sourcing capability of the

drive.
