Note 2: Current into a pin is defined as positive. Current out of a pin is defined as negative. All voltages are referenced to ground
except V
TH
and VTL.
Note 3: Maximum and minimum limits over temperature are guaranteed by design and characterization. Devices are production
tested at T
A
= +105°C.
Note 4: One output at a time.
Note 5: AC parameters are guaranteed by design and characterization, and are not production tested.
