description  
SN54ACT74 . . . FK PACKAGE  
(TOP VIEW)  
The ’ACT74 dual positive-edge-triggered devices  
are D-type flip-flops.  
Alowlevelatthepreset(PRE)orclear(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.

The SN54ACT74 is characterized for operation  
over the full military temperature range of –55°C  
to 125°C. The SN74ACT74 is characterized for  
operation from –40°C to 85°C.

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