SN74LVC126A - Quadruple Bus Buffer Gate With 3-State Outputs

The SN74LVC126A device is a quadruple bus buffer gate designed for 1.65-V to 3.6-V V_CC 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 3.3-V or 5-V devices. This feature allows the use of this device as a translator in a mixed 3.3-V and 5-V system environment.
