Functional Description
The ’AC/’ACT174 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 in-
put’s state is transferred to the corresponding flip-flop’s out-
put following the LOW-to-HIGH Clock (CP) transition. A LOW
input to the Master Reset (MR) will force all outputs LOW in-
dependent of Clock or Data inputs. The ’AC/’ACT174 is use-
ful for applications where the true output only is required and
the Clock and Master Reset are common to all storage
elements.
