74F174 Hex D-Type Flip-Flop with Master Reset April 1988 Revised July 1999 74F174 Hex D-Type Flip-Flop with Master Reset General Description The 74F174 is a high-speed hex D-type flip-flop. The device is used primarily as a 6-bit edge-triggered storage register. The information on the D inputs is transferred to storage during the LOW-to-HIGH clock transition. The device has a Master Reset to simultaneously clear all flipflops.

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.
