NSC 54F174DM

54F/74F174 Hex D Flip-Flop with Master Reset
General Description
Features
The ’F174 is a high-speed hex D 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.

Functional Description
Truth Table
The ’F174 consists of six edge-triggered D 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 ’F174 is useful for
applications where the true output only is required and the
Clock and Master Reset are common to all storage elements.
