Quad D Flip−Flop With Master Reset
The MC74AC/ACT175 is a high−speed quad D flip−flop. The device is useful for general flip−flop requirements where clock and clear inputs are common. The information on the D inputs is transferred to storage during the LOW−to−HIGH clock transition. The device has a Master Reset to simultaneously clear all flip−flops, when MR is low.
The MC74AC/ACT175 consists of four edge−triggered D flip−flops with individual D inputs and Q 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 Q outputs LOW and Q outputs HIGH independent of Clock or Data inputs. The MC74AC/ACT175 is useful for applications where the Clock and Master Reset are common to all storage elements.
