Product data sheet
1. General description
The 74AHC1G79-Q100; 74AHCT1G79-Q100 is a single positive-edge triggered D-type flip-flop. Data at the D-input that meets the set-up and hold time requirements on the LOW-to-HIGH clock transition will be stored in the flip-flop and appear at the Q output. Inputs are overvoltage tolerant. This feature allows the use of these devices as translators in mixed voltage environments.
This product has been qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 1) and is suitable for use in automotive applications.
2. Features and benefits
