DS4125–DS4776 ABSOLUTE MAXIMUM RATINGS

ELECTRICAL CHARACTERISTICS

(VCC = 3.135V to 3.465V, TA = -40°C to +85°C, unless otherwise noted.) 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 specificatio ns is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Soldering Temperature Profile J-STD-020 Specification.

Revision History

0 7/07 Initial release. — Added DS4150, DS4250, DS4300. All Removed fINITIAL from the frequency stability calculation in Note 3. 3 1 3/08 In the Pin Description, changed the EP description to indicate that it should not be connected and to avoid placing exposed metal under the pad location. 4 2 6/08 Removed future status from the DS4150, DS4250, and DS4300. 1, 6
