Overview
The 74AHC1G79GW/C125, produced by Nexperia (previously part of NXP USA Inc.), is a single positive-edge triggered D-type flip-flop. This component is part of the AHC (Advanced High-speed CMOS) logic family, known for its high speed and low power consumption. The flip-flop stores data at the D-input that meets the set-up and hold time requirements on the LOW-to-HIGH clock transition, and this data appears at the Q output. This device is particularly useful in mixed voltage environments due to its overvoltage tolerant inputs.
