ABSOLUTE MAXIMUM RATINGS
Voltage on Any Pin Relative to Ground -0.5V to +7.0V
Operating Temperature -55°C to +100°C
Storage Temperature -55°C to +100°C
This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operation
sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods of time may affect device
reliability.
