Flip-Flop in Digital Electronics: Types, Truth Table, Logic Circuit and Practical Demonstration
- 2. What is a Flip-Flop in Digital Electronics? A flip-flop is a bistable device that stores one bit of data. Defined as: "A bistable device with synchronous inputs that changes state only at specified transitions of a clock signal" — IEEE 91/1984. Key features: Maintains state (0 or 1) until the next clock transition. Enables memory, state control, and synchronization in digital circuits.

- 4. Types of Flip-Flops in Digital Electronics Set input = 1 →Output becomes 1 (stores 1). Reset input = 1 →Output becomes 0 (clears it). S = R = 0 →Output holds previous value (no change). S = R = 1 →Invalid condition (not allowed in basic SR). Used in simple memory circuits for on/off states Q - Output Q - output inverted
- 5. Types of Flip-Flops in Digital Electronics Only one input (D) controls output value. On clock edge, output becomes equal to D input. No invalid state like SR; safer to use. Stores one stable bit on each clock pulse. Used in shift registers and memory units. Q - Output Q - output inverted Q - Output Q - output inverted
- 6. Types of Flip-Flops in Digital Electronics J = 1, K = 0 →Sets output to 1. J = 0, K = 1 →Resets output to 0. J = K = 0 →Output stays the same. J = K = 1 →Output toggles (flips to opposite value). Used in counters, registers, and control circuits. Q - Output Q - output inverted
- 7. Types of Flip-Flops in Digital Electronics T = 0 →No change in output. T = 1 →Output flips on every clock pulse. Very useful for binary counting and frequency division. Can be made using JK flip-flop with J = K = T. Common in digital clocks and frequency counters. Q - Output Q - output inverted

Comparison Between the Types of Flip-Flop Flip-Flop Type Inputs Main Function Toggle Support Invalid State Common Applications SR Flip-Flop S (Set), R (Reset) Stores 1 (Set) or 0 (Reset) No Yes (S = R = HIGH) Simple control circuits, basic memory units D Flip-Flop D (Data) Locks input at clock edge No No Registers, data latches, CPU pipelines JK Flip-Flop J, K Improved SR; adds toggle ability Yes No Counters, frequency dividers, control logic T Flip-Flop T (Toggle) Toggles output on every clock edge Yes No Binary counters, toggle switches, blinking LEDs
