CD4027BC Dual J-K Master/Slave Flip-Flop with Set and Reset
CD4027BC
Dual J-K Master/Slave Flip-Flop with Set and Reset
General Description
The CD4027BC dual J-K flip-flops are monolithic comple-
mentary M OS (CMOS ) integr ated circuits c onstruc ted with
N- and P-channel enhancement mode transistors. Each
flip-flop has independent J, K, se t, reset, and clock inp uts
and buffered Q and Q outputs. These flip-flops are edge
sensitive to the clock input and change state on the posi-
tive-going transition of the clock pulses. Set or reset is
independent of the clock and is accomplished by a high
level on the respect i ve input.
All inputs are protected against damage due to static dis-
charge by diode clamps to VDD and VSS.
Features
Wide supply voltage rang e: 3.0V to 15V
High noise immunity: 0.45 VDD (typ.)
Low power TTL compatibility: Fan out of 2 driving 74L
or 1 driving 74LS
Low power: 50 nW (typ.)
Medium speed operation: 12 MHz (typ.) with 10V
supply
Ordering Code:
Devices also available in Tape and R eel. Speci fy by append ing the suffix let t er “X” to the orderin g c ode.
