NOTES:
2. 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.
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 “0.6 unit load (UL)” transceivers. The RS-485 standard allows up to 32 Unit Loads on the bus, so
a 0.6UL transceiver permits > 50 devices on the bus.
6. This is the part-to-part skew between any two units tested with identical test conditions (Temperature, V
CC
, etc.).
