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
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 ’AC/’ACT174
is useful for applications where the true output only is re-
quired and the Clock and Master Reset are common to all
storage elements.
