2 / 19 page +3.3V Multiprotocol Software-Selectable Cable Terminators and Transceivers 2 _______________________________________________________________________________________ ABSOLUTE MAXIMUM RATINGS ELECTRICAL CHARACTERISTICS (VCC = +3.3V ± 5%, TA = TMIN to TMAX. Typical values are at VCC = +3.3V, TA = +25°C, unless otherwise noted. See Note 2 for V+ and V- input voltage conditions.) 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. Note 1: V+ and V- can have maximum magnitudes of 7V, but their absolute difference cannot exceed 13V. (All voltages referenced to GND unless otherwise noted.)
