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 pull-down resistor; the minimum value of the resistor is determined by the current-sourcing capability of the drive.
