Enhanced product 2-ch, 1.65-V to 5.5-V buffers with 3-state outputs

This dual bus buffer gate is designed for 1.65-V to 5.5-V VCC operation.

The SN74LVC2G126 is a dual bus driver/line driver with 3-state outputs. The outputs are disabled when the associated output-enable (OE) input is low.

To ensure the high-impedance state during power up or power down, OE should be tied to GND through a pulldown resistor; the minimum value of the resistor is determined by the current-sourcing capability of the driver.

This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.
