FACT DATA
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.
Outputs Source/Sink 24 mA
ACT175 Has TTL Compatible Inputs
