Description

Features, Applications

The 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 stored during the LOW-to-HIGH clock transition. Both true and complemented outputs of each flip-flop are provided. A Master Reset input resets all flip-flops, independent of the Clock or D inputs, when LOW. Buffered positive edge-triggered clock Asynchronous common reset True and complement output Outputs source/sink mA 'ACT175 has TTL-compatible inputs Standard Microcircuit Drawing (SMD) 'ACT175: 5962-89693

FACT is a registered trademark of Fairchild Semiconductor Corporation.

The 'AC/'ACT175 consists of four edge-triggered D flip-flops 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 LOW-to-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.

H = HIGH Voltage Level L = LOW Voltage Level tn = Bit Time before Clock Pulse tn+1 = Bit Time after Clock Pulse

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. National does not recommend operation of FACT � circuits outside databook specifications.
