All Other Pins
2. All currents into device pins are positive; all currents out of device pins are negative. All voltages are referenced to device ground unless
3. Supply current specification is valid for loaded drivers when DE = 0V.
4. Applies to peak current. See “Typical Performance Curves” for more information.
5. Devices meeting these limits are denoted as “single unit load (1 UL)” transceivers. The RS-485 standard allows up to 32 Unit Loads on the bus.
6. Guaranteed by characterization, but not tested.
