These dual positive-edge-triggered D-type flip-  
flops are designed for 2.7-V to 5.5-V V  
operation.

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) inputs meeting  
the setup-time requirements is transferred to the  
NC – No internal connection  
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 the D input can be changed  
without affecting the levels at the outputs.  
The SN74LV74 is available in TI’s shrink small-outline package (DB), which provides the same I/O pin count  
and functionality of standard small-outline packages in less than half the printed-circuit-board area.  
The SN54LV74 is characterized for operation over the full military temperature range of –55°C to 125°C. The  
SN74LV74 is characterized for operation from –40°C to 85°C.
