HCF4027B is a monolithic integrated circuit fabricated in Metal Oxide Semiconductor technology available in DIP and SOP packages.
HCF4027B is a single monolithic chip integratedcircuit containing two identicalcomplementary-symmetry J-K master-slave flip-flops.
Each flip-flop has provisions for individual J, K, Set, Reset, and Clock input signals.
Buffered Q and Q signals are provided as outputs.
This input-output arrangement provides for compatible operation with the HCF4013B dual D type flip-flop.
This device is useful in performing control, register, and toggle functions.
Logic levels present at the J and K inputs, along with internal self-steering, control the state of each flip-flop; changes in the flip-flop state are synchronous with
the positive-going transition of the clock pulse.
Set and Reset functions are independent of the clock and are initiated when a high level signal is present at either the Set or Reset input.
