The CD4027 is a dual J-K master-slave flip-flop integrated circuit that contains two identical flip-flops. It is commonly used for data storage and in digital circuits like counters, control registers, and toggles. Each of the two flip-flops on the chip has independent clock, set, reset, J, and K inputs, and provides buffered Q and Q’ (complementary) outputs. Changes in the flip-flop’s state are synchronous with the rising edge of the clock signal, while the set and reset functions work independently of the clock.�

This CD4027IC is used for storing data and in performing control, register, and toggle functions. In toggling applications, it is used to alter the signal by control inputs. You can also use this IC in latching devices due to its property of storing data and determining the output based on the previous output.
CD4027 has two flip flops each having independent four inputs and two outputs that work opposite to each other. The input pins J and K control the state of flip flop which occurs at the positive transition of clock pulse. We can provide a clock signal through a push button or a PWM signal. Set and reset pins are independent of the clock. They are initiated by applying a High signal on these pins. Pin 8 is connected to the ground. Connect pin 16 with power supply and switch on the supply.
