Flip flop and rs latch

These Slides are for those whom complaining that we read hunderds of books but we could undersand the opereaion or working of f/f.
Just view this and you will be understand every thing... for Electronics and for IT both its good.

1. Flip Flop Introduction and RS Latch Special Slides for BSIT 3rd Morning And Evening Made by:Israr Ahmed BSIT 5 th Evening University of Education Lahore Okara campus ( Renala Khurd ) Ask Your Queries at.. [email protected]

2. Flip Flop In electronics, a flip-flop or latch is a circuit that has two stable states and can be used to store state information. (Wikipedia)

3. Types of Flip Flop Flip Flop ( Known as Latch ) (Known as F/F) Asynchronous Synchronous RS Latch Clock RS F/F JK Flip Flop

4. Difference Between Synchronous & Asynchronous Asynchronous: Output change immediately when input changes. Its event driven. . Synchronous: Output change but according to clock pulse not Immediately in many times. Its clock pulse driven.

5. RS Latch It’s a block diagram of RS Latch.

6. Logical Diagram for RS Latch Active Low Latch (Using Nand Gates)

7. Truth Table for RS Latch It’s a truth table for RS Latch using Nand Gates.

8. Description about RS Latch It has two Inputs S and R Input S means set & input R m eans r eset It has two outputs Q and Q’ No clock pulse are used in a latch It can store 1 bit of data (either 1 or 0) It has two states whether set or reset In set condition it store 1 bit And in reset condition it store 0 bit

9. Description about RS Latch (Cont..) Its asynchronous device Inputs change output immediately when input changes. When S=1 and R=0 0n input then it will reset (store 0 bit) When S=0 and R=1 on input then it will set (store 1 bit)
