DS75LV
Digital Thermometer and Thermostat
Absolute Maximum Ratings
Voltage on VDD, Relative to Ground.....................-0.3V to +4.0V
Voltage on Any Other Pin, Relative to Ground ....-0.3V to +6.0V
Operating Temperature Range.......................... -55°C to +125°C
Storage Temperature Range............................. -55°C to +125°C
Lead Temperature (soldering, 10s).................................. +260°C
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these
or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.
