Difference between revisions of "JK flip-flop"

Simultaneous two-stage JK flip-flop, changes its internal state on the rising edge at the input "C", depending on the status of the inputs «J» and «K», then at the falling edge on the input «C» copies its internal state to the output.

Variants of the flip-flop, depending on its inputs states:

• If the input «J» = 0 and «K» = 0 - the internal state will not change;
• If the input «J» = 0 and «K» > 0 - the internal state becomes zero
• If the input «J» > 0 and «K» = 0 - the internal state becomes equal to the value of «J»
• If the input «J» > 0 and «K»> 0, then:
  • if the current internal state is zero, it will become equal to the value of «J» input
  • if the current output value is not zero, then it becomes zero

In the time interval between edges on the input «C» the internal state and the state of the flip-flop output remain unchanged regardless of the inputs «J» or «K» values.
