CC The MAX14535EMAX14539E operate from a +2.4V to TOP VIEW +5.5V supply. These devices can be powered from the typical analog supply voltage in a cell phone (+2.5V to +2.8V) or a lithium-ion (Li+) battery (about 4.3V max). 7 6 NC1 8 5 NC2 The MAX14535EMAX14539E have high ESD protec- tion, up to 15kV on COM , and the NC , NO , and COM1 9 4 COM2 MAX14535E COM voltage can go up to 3.6V when V = 0 without CC MAX14539E damaging the devices.

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. ELECTRICAL CHARACTERISTICS (V = +2.4V to +5.5V, T = -40C to +85C, unless otherwise noted.
