TECHNICAL DATA  
IN74LV174  
Hex D-type flip-flop with reset; positive edge-trigger  
The 74LV174 is a low–voltage Si–gate CMOS device and is pin and  
function compatible with the 74HC/HCT174.  
The 74LV174 has six edge–triggered D–type flip–flops with individual D  
inputs and Q outputs. The common clock (CP) and master reset (MR)  
inputs load and reset (clear) all flip–flops simultaneously.  
The register is fully edge–triggered. The state of each D input, one set–  
up time prior to the LOW–to–HIGH clock transition, is transferred to the  
corresponding output of the flip–flop.  
A LOW level on the MR input forces all outputs LOW, independently of  
clock or data inputs.  
The device is useful for applications requiring true outputs only and  
clock and master reset inputs that are common to all storage elements.
