1 / 6 page 5-1 FACT DATA Quad D FlipFlop 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 Pinout: 16-Lead Packages (Top View) 15 16 14 13 12 11 10 2 1 3 4 5 6 7 VCC 9 8 Q3 Q3 D3 D2 Q2 Q2 CP MR Q0 Q0 D0 D1 Q1 Q1 GND PIN NAMES Data Inputs Clock Pulse Input Master Reset Input Outputs Outputs D0 – D3 CP MR Q0 – Q3 Q0 – Q3 TRUTH TABLE Inputs Outputs MR CP D Qn Qn L X X L H H H H L H L L H H L X Qn Qn H = HIGH Voltage Level L = LOW Voltage Level X = Immaterial = LOW-to-HIGH Transition of Clock MC74AC175 MC74ACT175 QUAD D FLIP-FLOP WITH MASTER RESET N SUFFIX CASE 648-08 PLASTIC D SUFFIX CASE 751B-05 PLASTIC LOGIC SYMBOL D0 D1 D2 D3 Q0 Q0 Q1 Q1 Q2 Q2 Q3 Q3 CP MR |
