Maxim Integrated
Low-Current I2C RTCs for High-ESR Crystals
DS1341/DS1342
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.
Voltage Range on Any Pin Relative to Ground....-0.3V to +6.0V
Operating Temperature Range.......................... -40NC to +85NC
Junction Temperature Maximum.....................................+150NC
Storage Temperature Range............................ -55NC to +125NC

DC ELECTRICAL CHARACTERISTICS
(VCC = +1.8V to +5.5V, TA = -40NC to +85NC, unless otherwise noted.) (Note 2)
ABSOLUTE MAXIMUM RATINGS
Note 1: Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-layer
board. For detailed information on package thermal considerations, refer to www.maximintegrated.com/thermal-tutorial.
