NOTES FOR
CMOS DEVICES
1
VOLTAGE APPLICATION WAVEFORM AT INPUT PIN Waveform distortion due to input noise or a reflected wave may cause malfunction.
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).
