ABSOLUTE MAXIMUM RATINGS
Voltage Range on any Pin Relative to Ground………………………………….…………-0.3V to +6.0V
Operating Temperature Range…………………………………………………………..…...0°C to +70°C
Storage Temperature Range…………………………………………………………..…...-40°C to +85°C
Lead Temperature (soldering, 10s) ………................................................................................…...+260°C
Note: Wave or hand-solder only.
This is a stress rating only and functional operation of the device at these or any other conditions beyond those indicated in the operation
sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods of time can affect reliability.
