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 Pchannel 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 discharge by diode clamps to VDD and VSS
