The term “ Flip-flop” relates to the actual operation of the device, as it can be “flipped” into one logic Set state or “flopped” back into the opposing logic Reset state. Then the SR flip-flop actually has three inputs, Set, Reset and its current output Q relating to it’s current state or history. The reset input resets the flip-flop back to its original state with an output Q that will be either at a logic level “1” or logic “0” depending upon this set/reset condition.Ī basic NAND gate SR flip-flop circuit provides feedback from both of its outputs back to its opposing inputs and is commonly used in memory circuits to store a single data bit.

Then the SR description stands for “Set-Reset”. This simple flip-flop is basically a one-bit memory bistable device that has two inputs, one which will “SET” the device (meaning the output = “1”), and is labelled S and one which will “RESET” the device (meaning the output = “0”), labelled R. The SR flip-flop, also known as a SR Latch, can be considered as one of the most basic sequential logic circuit possible. However, we can see how feedback works by examining the most basic sequential logic components, called the SR flip-flop.

Unfortunately, this configuration never changes state because the output will always be the same, either a “1” or a “0”, it is permanently set.

The two inverters or NOT gates are connected in series with the output at Q fed back to the input.
