What is the purpose of 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 – a bistable multivibrator. The circuit can be made to change state by signals applied to one or more control inputs and will have one or two outputs.
Why is the JK flip flop used in counters?
The JK flip flop is basically a gated SR flip-flop with the addition of a clock input circuitry that prevents the illegal or invalid output condition that can occur when both inputs S and R are equal to logic level “1”.
What are the pins on a JK flip flop clock?
In general it has one clock input pin (CLK), two data input pins (J and K) and two output pins (Q and Q̅…) as shown by Figure 1. JK flip-flop can either be triggered upon the leading-edge of the clock or on its trailing edge and hence can either be positive- or negative- edge triggered, respectively.
When does a JK flip flop reset the circuit?
When both the J and K input are at logic “1” at the same time and the clock input is pulsed HIGH, the circuit toggle from its SET state to a RESET or visa verse. When both the terminals are HIGH the JK flip-flop acts as a T type toggle flip-flop.
Who is the inventor of the JK flip flop?
The JK Flip Flop name has been kept on the inventor name of the circuit known as Jack Kilby. The basic symbol of the JK Flip Flop is shown below: The basic NAND gate RS flip-flop suffers from two main problems.
