ABSOLUTE MAXIMUM RATINGS
Voltage Range on Any Pin Relative to Ground……………………………………..-0.3V to +6.0V
Storage Temperature Range………………………………………………………...-40°C to +85°C
Soldering Temperature (EDIP, leads)..……………………..+260°C for 10 seconds (See Note 7)
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 reliability.
