FUNCTIONAL DESCRIPTION
The LS174 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
LS174 is useful for applications where the true output only
is required and the Clock and Master Reset are common to
all storage elements.
