ABSOLUTE MAXIMUM RATINGS
Voltage Range on Any Pin Relative to Ground……………………………………………..-0.3V to +7.0V
Storage Temperature……………………………………………………...-40°C to +85°C, Noncondensing
Soldering Temperature……………………………..…+260°C for 10 seconds (DIP Package) (See Note 7)
See IPC/JEDEC Standard J-STD-020A for Surface-Mount Devices
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.
