3 Description

The SNx4AHC126 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.
