2. What is Flip flop >>In digital circuits, the flip-flop, is a kind of bi-stable multivibrator . >>It is a Sequential Circuits / an electronic circuit which has two stable states and thereby is capable of serving as one bit of memory , bit 1 or bit 0

3. Introduction : Types Of Flip Flop 1. SR Flip Flop a.SR Flip Flop Active Low = NAND gates b. SR Flip Flop Active High = NOR gates 2. Clocked SR Flip Flop 3. JK Flip Flop 4 . T Flip Flop 5 . D Flip Flop 6 . Master-Slave Edge-Triggered Flip-Flop

4. The Used of Flip Flop For Memory circuits For Logic Control Devices For Counter Devices For Register Devices

5. SR Flip Flop - NOR GATE LATCH S R Q 0 0 Q 0 1 1 0 1 1 1 Q = Q ’ =0 No change Reset Set Invalid

6. SR Flip Flop - NAND GATE LATCH S R Q 0 0 Q = Q ’ =1 0 1 1 1 0 1 1 Q Invalid Set Reset No change

7. Clocked SR Flip Flop C S R Q 0 x x Q 1 0 0 Q 1 0 1 1 1 0 1 1 1 1 Q = Q ’ No change No change Reset Set Invalid

8. JK Flip Flop

9. T Flip Flop

10. T Flip Flop

11. D Flip Flop C D Q 0 x Q 1 1 1 1 No change Reset Set Also Known as Data Flip flop Can be constructed from RS Flip Flop or JK Flip flop by addition of an inverter
