SN74AUP1G126 - Low-Power Single Bus Buffer Gate with 3-State Output

The AUP family is TI’s premier solution to the industry’s low-power needs inbattery-powered portable applications. This family assures a very low static and dynamic powerconsumption across the entire V_CC range of 0.8 V to 3.6 V, resulting in anincreased battery life. This product also maintains excellent signal integrity (seeAUP – The Lowest-Power Family and Excellent Signal Integrity ).

This bus buffer gate is a single line driver with a 3-state output. The output isdisabled when the output-enable (OE) input is low. This device has the input-disable feature, whichallows floating input signals.

To assure 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.

NanoStar™ package technology is a majorbreakthrough in IC packaging concepts, using the die as the package.

This device is fully specified for partial-power-down applications usingI_off. The I_off circuitry disables the outputs whenthe device is powered down. This inhibits current backflow into the device which prevents damage tothe device.
