Overview
The 74AHC1G79GW-Q100 is a single positive-edge triggered D-type flip-flop produced by Nexperia, which was previously part of NXP Semiconductors. This device is designed to store data at the D-input that meets the set-up and hold time requirements on the LOW-to-HIGH clock transition, and it appears at the Q output. It is part of the AHC (Advanced High-speed CMOS) family and is known for its high-speed operation and low power consumption.
This component has been qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 1), making it suitable for use in automotive applications. It operates over a wide supply voltage range from 2.0 to 5.5 V and features overvoltage tolerant inputs up to 5.5 V, which allows it to be used in mixed voltage environments.
