description/ordering information  
The ’ACT74 dual positive-edge-triggered devices are 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.
