The ’HCT74 contain two independent D-type  
positive-edge-triggered flip-flops. A low level at  
the preset (PRE) or clear (CLR) inputs 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 are transferred to the outputs  
on the positive-going edge of the clock (CLK)  
pulse. Clock triggering occurs at a voltage level  
and is not directly related to the rise time of CLK.  
Following the hold-time interval, data at the  
D input may be changed without affecting the  
levels at the outputs.

This configuration is unstable; that is, it does not  
persist when PRE or CLR returns to its inactive  
(high) level.
