CD4027BM CD4027BC Dual J-K Master Slave
Flip-Flop with Set and Reset
General Description
These 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
All inputs are protected against damage due to static dis-
charge by diode clamps to VDD and VSS
