DS1673
ABSOLUTE MAXIMUM RATINGS
Voltage on Any Pin Relative to Ground…………………………………………………….-0.3V to +7.0V
Operating Temperature………………………………………………………………………..0°C to +70°C
Storage Temperature……………………………………………………………………….-55°C to +125°C
Soldering Temperature………………………………………………………..See 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 device reliability.
