3 Description

The SN74LVC126A device is a quadruple bus buffer

gate designed for 1.65V to 3.6V VCC operation.

The SN74LVC126A device features independent line

drivers with 3-state outputs. Each output is disabled

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

To ensure the high-impedance state during power up

or power down, OE must be tied to GND through a

pulldown resistor; the minimum value of the resistor

is determined by the current-sourcing capability of the

driver.

Inputs can be driven from either 3.3V or 5V

devices. This feature allows the use of this device

as a translator in a mixed 3.3V and 5V system

environment.
