Question

What is the significance of the J and K terminals on the J-K flip-flop?

(a) There is no known significance in their designations

(b) The J represents “jump,” which is how the Q output reacts whenever the clock goes high and the J input is also HIGH

(c) The letters were chosen in honour of Jack Kilby, the inventory of the integrated circuit

(d) All of the other letters of the alphabet are already in use

I got this question by my school principal while I was bunking the class.

Enquiry is from Flip Flops in section Flip-Flops of Digital Circuits

Answer 1

Right choice is (c) The letters were chosen in honour of Jack Kilby, the inventory of the integrated circuit

For explanation: The letters J & K were chosen in honour of Jack Kilby, the inventory of the integrated circuit. In J&K flip-flops, the invalid state problem is resolved, thus leading to the toggling of states.
