SN74AUP1G240 - Low-Power Single Buffer/Driver 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 ).

This buffer/driver is a single line driver with a 3-state output. The output is disabledwhen the output-enable (OE) input is high. This device has the input-disablefeature, which allows floating input signals.

To assure the high-impedance state during power up or power down,OE should be tied to V_CC through a pullup resistor;the minimum value of the resistor is determined by the current-sinking capability of thedriver.

NanoStar™ package technology is a major breakthrough in IC packaging concepts, using thedie 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.
