Description

In the HCC/HCF4027B series, the HCC4027B (extended temperature range) and HCF4027B (intermediate temperature range) are monolithic integrated circuit, available in 16-lead dual in-line plastic or ceramic package and plastic micro package.

The HCC/HCF4027B 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 HCC/HCF4013B dual D-type flip-flop.

TheHCC/HCF4027B is useful in performing control, register, and toggle functions. Logic levels present at the J and Kinputs along with internal self-steering control the state of each flip-flop ; changes in the flipflop 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.
