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
tested at T

= +85°C.
Note 3: Parameters are guaranteed by design and characterization and are not production tested. Limits are set at ±6 sigma.
