Working Principles
The CD4027BME4 is a sequential logic device that consists of two J-K master-slave flip-flops. Each flip-flop has its own J, K, Clock, Set (S), and Reset (R) inputs. The positive edge-triggered operation ensures that the flip-flops capture data on the rising edge of the clock signal.
The J and K inputs determine the behavior of the flip-flops based on their current state and the clock input. The Set and Reset inputs allow for direct overriding of the clock and force the flip-flops into specific states.
The buffered outputs provide improved noise immunity and can be used to drive other digital circuits.
