2 / 36 page DS28E04-100: 4096-Bit 1-Wire Addressable EEPROM with PIO 2 of 36 ABSOLUTE MAXIMUM RATINGS All Pins: Voltage to GND -0.5V, +6V All Pins: Sink Current 20mA Operating Temperature Range -40°C to +85°C Junction Temperature +150°C Storage Temperature Range -40°C to +85°C Soldering Temperature See IPC/JEDEC J-STD-020A 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.
