DESCRIPTION

The ’AHCT74 dual positive-edge-triggered devices are D-type flip-flops. low levelat the preset (PRE)or clear (CLR) inputs setsor resets the outputs, regardlessof the levelsof the
other inputs. When PRE and CLR are inactive (high), dataat the data (D) input meeting the setup time
requirementsis transferredto the outputs on the positive-going edgeof the clock pulse. Clock triggering occursa voltage level andis not directly relatedto the rise timeof the clock pulse. Following the hold-time interval,
dataat theD input canbe changed without affecting the levelsat the outputs.
