ABSOLUTE MAXIMUM RATINGS
Voltage Range on Any Pin Relative to Ground……………………………………………………….-0.3V to (VCC + 0.5V)
Voltage Range on VCC Relative to Ground..………………………………………………………………….-0.3V to +6.0V
Operating Temperature Range……………………………………………………………………………….-40°C to +85°C
Storage Temperature…………………………………………………………………………………………-55°C to +125°C
Soldering Temperature..………………………………………………………..See IPC/JEDEC J-STD-020 Specification
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.
