SEMICONDUCTOR TECHNICAL DATA
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.

†
This device contains protection circuitry to guard against damage
due to high static voltages or electric fields. However, precautions must
be taken to avoid applications of any voltage higher than maximum rated
voltages to this high-impedance circuit. For proper operation, V and

Unused inputs must always be tied to an appropriate logic voltage
level (e.g., either V or V ). Unused outputs must be left open.
