DS1682 Total-Elapsed-Time Recorder with Alarm
ABSOLUTE MAXIMUM RATINGS
Voltage Range on Any Pin Relative to Ground…….…………………………………………-0.3V to +6V
Operating Temperature Range……………………………………………….……………..-40°C to +85°C
Storage Temperature Range…………………………………………………..…………...-55°C to +125°C
Soldering Temperature………………………………………….See IPC/JEDEC J-STD-020 Specification
This is a stress rating only and functional operation of the device at these or any other conditions beyond those indicated in
the operation sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended
periods of time can affect device reliability.
