DS1307 64 x 8, Serial, I2C Real-Time Clock
ABSOLUTE MAXIMUM RATINGS
Voltage Range on Any Pin Relative to Ground .. -0.5V to +7.0V Operating Temperature Range (Noncondensing) Commercial .. 0°C to +70°C Industrial .. -40°C to +85°C Storage Temperature Range ... -55°C to +125°C Soldering Temperature (DIP, leads) .. +260°C for 10 seconds Soldering Temperature (surface mount)…..……………………….Refer to the JPC/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 the absolute maximum rating conditions for extended periods may affect device reliability.
