Functional Description
The AC/ACT175 consists of four edge-triggered D-type
flip-flops with individual D inputs and Q and Q outputs.
The Clock and Master Reset are common. The four flip-
flops will store the state of their individual D inputs on the
LOW-to-HIGH clock (CP) transition, causing individual Q
and Q outputs to follow. A LOW input on the Master
Reset (MR) will force all Q outputs LOW and Q outputs
HIGH independent of Clock or Data inputs. The AC/
ACT175 is useful for general logic applications where a
common Master Reset and Clock are acceptable.
