MAX14571/MAX14572/MAX14573

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.

ABSOLUTE MAXIMUM RATINGS

PACKAGE THERMAL CHARACTERISTICS (Note 2)

Note 1: DC current is also limited by the thermal design of the system.

TSSOP

Note 2: 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.
