SN74AUC1G126 - Single Bus Buffer Gate With 3-State Output

The SN74AUC1G126 bus buffer gate is operational at 0.8-V to 2.7-VV_CC, but is designed specifically for 1.65-V to 1.95-VV_CC operation.

The SN74AUC1G126 device is a single line driver with a tri-state output. The output isdisabled when the output-enable (OE) input is low.

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

NanoFree™ package technology is a major breakthrough in device packaging concepts, usingthe die as the package.

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