Overview
The SN74AUP1G79DCKR, produced by Texas Instruments, is a single positive-edge-triggered D-type flip-flop. This device is part of the AUP (Advanced Ultra-Low Power) family, which is designed to meet the industry's low-power needs in battery-powered portable applications. The SN74AUP1G79 ensures very-low static and dynamic power consumption across a wide supply voltage range of 0.8 V to 3.6 V, thereby increasing battery life. It maintains excellent signal integrity and is fully specified for partial-power-down applications using Ioff circuitry, which disables the outputs when the device is powered down to prevent current backflow and potential damage.
