Handling the Device
Preventing latch up
The CO4011 is a CMOS device and may suffer latch
up under the following conditions:
1) A voltage higher than VCC or lower than VSS
is applied to any pin.
2) Absolute maximum ratings are exceeded
3) AVCC power is provided before VCC supply
Handling unused Pins
Do not leave unused input pins open. This might
cause malfunction of the device.
Power Supply Pins
Make sure that all ground and power supply pins are
connected to the same potential. Do not leave any
ground or power pins open. Connect at least two
ceramic capacitors of 100 nF and a tantalium
capacitor of 1 uF between VCC and VSS as close as
possible to the device.
