6. All currents into device pins are positive; all currents out of device pins are negative. All voltages are referenced to device ground unless otherwise
7. Supply current specification is valid for loaded drivers when DE = 0V (RS-485 mode only).
8. Applies to peak current. See “Typical Performance Curves” starting on page 19 for more information.
