74F174 Hex D-Type Flip-Flop with Master Reset
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
flip-flops.

Unit Loading/Fan Out
Functional Description
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.
