The is a high-speed quad D-type flip-flop. The device is useful for general flip-flop requirements where clock and clear inputs are common. The information on the D-type inputs is stored during the LOW-to-HIGH clock transition. Both true and complemented outputs of each flipflop are provided. A Master Reset input resets all flip-flops, independent of the Clock or D-type inputs, when LOW.Features

Pin Names MR Q0Q3 Description Data Inputs Clock Pulse Input Master Reset Input True Outputs Complement Outputs
The AC/ACT175 consists of four edge-triggered D-type flipflops 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 LOWto-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.

Note 1: Absolute maximum ratings are those values beyond which damage to the device may occur. The databook specifications should be met, without exception, to ensure that the system design is reliable over its power supply, temperature, and output/input loading variables. Fairchild does not recommend operation of FACT circuits outside databook specifications
