If the input of the CMOS device stays in the area between VIL (MAX) and VIH (MIN) due to noise, etc., the device may malfunction. Take care to prevent chattering noise from entering the device when the input level is fixed, and also in the transition period when the input level passes through the area between VIL (MAX) and VIH (MIN). 2 HANDLING OF UNUSED INPUT PINS Unconnected CMOS device inputs can be cause of malfunctio.
