ABSOLUTE MAXIMUM RATINGS

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functionaloperation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure toabsolute maximum rating conditions for extended periods may affect device reliability.

Note 1: All currents into the device are positive. All currents out of the device are negative. All voltages referred to device ground,unless otherwise noted.

Note 2: This is a differential voltage from A to B that the driving device must see on the bus to disable its driver.Note 3: The short-circuit output current applied to peak current just prior to foldback current limiting. The short-circuit foldback out-

put current applies during current limiting to allow a recovery from bus contention.
