Functional Description
Truth Table
The AC/ACT174 consists of six edge-triggered D-type flip-
flops with individual D inputs and Q outputs. The Clock
Inputs
(CP) and Master Reset (MR) are common to all flip-flops.
Each D input’s state is transferred to the corresponding flip-
MR

flop’s output following the LOW-to-HIGH Clock (CP) transi-

tion. A LOW input to the Master Reset (MR) will force all
outputs LOW independent of Clock or Data inputs. The AC/
H
ACT174 is useful for applications where the true output

mon to all storage elements.
