The ’AC74 devices are dual positive-edge-  
triggered D-type flip-flops.

2Q  
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.
