ABSOLUTE MAXIMUM RATINGS
Voltage Range on Any Pin Relative to Ground..………………………………..…………..-0.3V to +6.0V
Storage Temperature Range……………………...………………..……..-40°C to +85°C (noncondensing)
Soldering Temperature………………...See IPC/JEDEC Standard J-STD-020 for Surface-Mount Devices.
See Note 7 for Through-Hole Mounted Devices.
This is a stress rating only and functional operation of the device at these or any other condition 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.
