DS1644/DS1644P
ABSOLUTE MAXIMUM RATINGS
Voltage Range on Any Pin Relative to Ground……………………………………………..-0.3V to +6.0V
Storage Temperature Range………………………………………………-40°C to +85°C, Noncondensing
Operating Temperature Range…….................…….......……………………0°C to +70°C, Noncondensing
Lead Temperature (soldering, 10s) ...................................................................................................+260°C
Soldering Temperature (reflow, PowerCap package) .......................................................................+260°C
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.
