1. General description

The 74AHC1G79; 74AHCT1G79 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.

2. Features and benefits
