The AUP family is TI’s premier solution to the industry’s low-power needs in battery-powered portable applications. This family assures a very-low static and dynamic power consumption across the entire V_CC range of 0.8 V to 3.6 V, thus resulting in an 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 the data (D) input meets the setup-time requirement, the data is transferred to the Q output on the positive-going edge of the clock pulse. Clock triggering occurs at a voltage level and is not directly related to the rise time of the clock pulse. Following the hold-time interval, data at the D input can be changed without affecting the levels at the outputs.

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

The SN74AUP1G79 device is fully specified for partial-power-down applications using I_off. The I_off circuitry disables the outputs when the device is powered down. This inhibits current backflow into the device which prevents damage to the device.
