Note 1:
Absolute Maximum Ratings are those values beyond which the life of
a device may be impaired.
Note 2:
All typicals are given for V

Note 3:
All currents into device pins are positive; all currents out of device
pins are negative. All voltages are referenced to device ground unless
otherwise specified.
Note 4:
For higher ambient temperatures, the part may enter thermal
shutdown during short-circuit conditions.
Note 5:
Both driver input and driver enable pins are pulled high
simultaneously.
Note 6:
Guaranteed by design.
Note 7:
Measured with an external LTC1485 driver.
