MC74AC175, MC74ACT175
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.
