DESCRIPTION
The ’AC74 devices are dual positive-edge-triggered D-type flip-flops.
A low level at the preset (PRE)\ or clear (CLR)\ input sets or resets the outputs, regardless of the levels of the other inputs. When PRE\ and CLR\ are inactive (high), data at the data (D) input
meeting the setup-time requirements is transferred to the outputs on the positive-going edge of the clock pulse. Clock triggering occurs at a voltage level and is not directly related to the rise time
of the clock pulse. Following the hold-time interval, data at D can be changed without affecting the levels at the outputs.
