U74AC74
Overview
The U74AC74 is a dual positive-edge-triggered D-type flip-flop. The preset ( PRE ) and clear ( CLR ) input can set or reset the output at a low level ,regardless of the level of others inputs .when the PRE and CLR are inactive(high), data at the data D input meeting the set-up time requirements is transferred to the outputs on the positive-going edge of the clock pulse.
- Operating voltage rauge: VCC(OPR)=2V to 6V * Inputs accept voltages to 6V * Max tPD at 10ns of 5V
