SN74AUP1G79 - Low-Power Single Positive-Edge-Triggered D-Type Flip-Flop

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, thus resulting inan increased battery life. The AUP devices also maintain excellent signal integrity.

The SN74AUP1G79 is a single positive-edge-triggered D-type flip-flop. When data at thedata (D) input meets the setup-time requirement, the data is transferred to the Q output on thepositive-going edge of the clock pulse. Clock triggering occurs at a voltage level and is notdirectly related to the rise time of the clock pulse. Following the hold-time interval, data at theD input can be changed without affecting the levels at the outputs.

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

The SN74AUP1G79 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.
