CD4027BE (TEXAS INSTRUMENTS)

The CD4027BE is a Single Monolithic Chip Integrated Circuit, containing two identical complementary-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 RCA-CD4013B dual D-type flip-flop. The CD4027BE 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.
