4027 CMOS 带置位复位双J-K主从触发器

The CD4027BC dual J-K flip-flops are monolithic complementary

MOS (CMOS) integrated circuits constructed with

N- and P-channel enhancement mode transistors. Each

flip-flop has independent J, K, set, reset, and clock inputs

and buffered Q and Q outputs. These flip-flops are edge

sensitive to the clock input and change state on the positive-

going transition of the clock pulses. Set or reset is

independent of the clock and is accomplished by a high

level on the respective input.
