SN74AUP1G79

低功耗单路上升沿 D 类触发器

The AUP family is ’s premier solution to the industry&3146;s low-power needs in battery-powered portable applications. This family ensures a very low static and dynamic power consumption across the entire VCC 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 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 Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.
