NOTES:
10. 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.

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. When testing the ISL8483, keep RE = 0 to prevent the device from entering SHDN.
6. When testing the ISL8483, the RE signal high time must be short enough (typically <200ns) to prevent the device from entering SHDN.
7. The ISL8483 is put into shutdown by bringing RE high and DE low. If the inputs are in this state for less than 50ns, the parts are guaranteed not

9. Set the RE signal high time >600ns to ensure that the device enters SHDN.
