Note 1: Current into a pin is defined as positive. Current out of a pin is defined as negative. All voltages are referenced to ground
Note 2: Maximum and minimum limits over temperature are guaranteed by design and characterization. Devices are production
Note 3: Guaranteed by design and characterization.
Note 4: Short only one output at a time. Do not exceed the absolute maximum junction temperature specification.
