DS7505
Digital Thermometer and Thermostat
Absolute Maximum Ratings
Voltage Range on VDD Relative to Ground..........-0.3V to +4.0V
Voltage Range 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
Soldering Temperature.......................... Refer to the IPC/JEDEC
J-STD-020 Specification.
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.
