– 2000-V Human-Body Model (A114-A)

– 200-V Machine Model (A115-A)

This quadruple bus buffer gate is designed for 1.65-V

The SN74LVC126A features independent line drivers

with 3-state outputs. Each output is disabled when

the associated output-enable (OE) input is low.

pulldown resistor; the minimum value of the resistor is determined by the current-sourcing capability of the driver.

Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of this device as a translator in

a mixed 3.3-V/5-V system environment.
