Functional Description  
Truth Table  
The 74F174 consists of six edge-triggered D-type flip-flops  
with individual D inputs and Q outputs. The Clock (CP) and  
Master Reset (MR) are common to all flip-flops. Each D  
input’s state is transferred to the corresponding flip-flop’s  
output following the LOW-to-HIGH Clock (CP) transition. A  
LOW input to the Master Reset (MR) will force all outputs  
LOW independent of Clock or Data inputs. The 74F174 is  
useful for applications where the true output only is  
required and the Clock and Master Reset are common to  
all storage elements.
