Overview
The SN74LVC1G80-Q1 is an automotive AEC-Q100 qualified, single positive-edge-triggered D-type flip-flop designed by Texas Instruments. This device operates over a wide voltage range of 1.65 V to 5.5 V, making it versatile for various automotive applications. The flip-flop transfers data from the input (D) to the output (Q) on the positive-going edge of the clock pulse, provided the setup time requirement is met. The clock triggering is based on voltage levels and is independent of the clock pulse rise time, allowing data changes at the input without affecting the output after the hold-time interval.
