ABSOLUTE MAXIMUM RATINGS

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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional opera-

tion 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.

PACKAGE THERMAL CHARACTERISTICS (Note 2)

ELECTRICAL CHARACTERISTICS

(VCC = +3.0V to +3.6V, CCL = 200nF coupling capacitor on each output, RL = 50I on each output, TA = 0NC to +70NC, unless oth-

erwise noted. Typical values are at VCC = +3.3V and TA = +25NC.) (Note 3)

Note 1: All I/O pins are clamped by internal diodes.
