The MC14027B dual J–K flip–flop has independent J, K, Clock (C), Set (S) and Reset (R) inputs for each flip–flop. These devices may be used in control, register, or toggle functions.

• Diode Protection on All Inputs
• Supply Voltage Range = 3.0 Vdc to 18 Vdc
• Logic Swing Independent of Fanout
• Logic Edge–Clocked Flip–Flop Design — Logic state is retained indefinitely with clock level either high or low; information is transferred to the output only on the positive–going edge of the clock pulse
• Capable of Driving Two Low–power TTL Loads or One Low–power Schottky TTL Load Over the Rated Temperature Range
• Pin–for–Pin Replacement for CD4027B
