NOTES:
8. 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.
9. Supply current specification is valid for loaded drivers when DE = 0V.
10. Applies to peak current. See “Typical Performance Curves” beginning on page 18 for more information
11. Keep RE = 0 to prevent the device from entering SHDN.
12. The RE signal high time must be short enough (typically <100ns) to prevent the device from entering SHDN.
13. Transceivers (except on the ISL31485E) are put into shutdown by bringing RE high and DE low. If the inputs are in this state for less than 60ns, the
parts are guaranteed not to enter shutdown. If the inputs are in this state for at least 600ns, the parts are guaranteed to have entered shutdown. See
14. Keep RE = VCC, and set the DE signal low time >600ns to ensure that the device enters SHDN.
15. Set the RE signal high time >600ns to ensure that the device enters SHDN.
16. Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise specified. Temperature limits established by characterization
and are not production tested.
17. Tested according to TIA/EIA-485-A, Section 4.2.6 (±80V for 15ms at a 1% duty cycle).
18. Does not apply to the ISL31485E. The ISL31485E has no Rx enable function, and thus no SHDN function.
19. See “Caution” statement under the “Recommended Operating Conditions” section on page 8.
