Realisation of Flipflops using NAND Gates

REALISATION OF FLIPFLOPS USING NAND GATES

AIM:

To set up and test the following flipflops using ICs 7400 and 7410.

 (1) SR FF(2) JK FF(3)D FF (4) T FF(5) MS JK FF

MATERIALS AND TOOLS REQUIRED:

                       Digital IC trainer kit, ICs 7486, 7408, Power supply.

THEORY:

Flip flops are synchronous bi stable devices. The term synchronous implies that output changes state only at specified point of a trigger input called the clock. A flip-flop has two stages 0 or1. Set is state 1 and 0 is the reset state. The output state for any input depends on past input and data inputs present at that instant. The state may change only when a clock is applied.

PROCEDURE:

            The circuits are set up on the breadboard in the trainer kit. The logic inputs and clock are applied. The truth table of various flipflops is verified by observing the outputs.

RESULT:

Given flip-flops are realized using ICs 7400 and 7410.
