CD4027 – Dual JK FlipFlop
CD4027 – Dual JK FlipFlop, When we want to use flip-flops with CMOS. Often we meet CD4027. It is dual J-K flip-flops that are monolithic complementary MOS integrated circuits.
We have seen many circuits that use them. Of course, making a great circuit we should understand detail of any parts( basic enough).
Slow down!
If you are beginner. You should read how flip-flop works below.
Pin Configuration Description
This CD4027 IC has a total of 16 pins. As it is a dual flip flop IC, so it has 2 flip flops. All the pins, their name, and description are mentioned in the table given below.
