set to simultaneously clear all flip-flops.
and Q outputs. The Clock (CP) and Master Reset (MR) are common to all
flip-flops. The state of each D input, one setup time before low-to-high clock
transition, is transferred to the corresponding flig-flop’s Q output. A LOW input
to the Master Reset (MR) will force all outputs LOW independent of Clock or
Data inputs. The F174 is useful for applications where only the true output is
required and the Clock and Master Reset are common to all storage elements.
The MC54/74F174 is a high-speed hex D flip-flop. The device is used pri-
The F174 consists of six edge-triggered D flip-flops with individual D inputs
