Electrical Specifications
NOTES:
10. All currents into device pins are positive; all currents out of device pins are negative. All voltages are referenced to device
11. Supply current specification is valid for loaded drivers when DE = 0V.
12. Applies to peak current. See “Typical Performance Curves” beginning on page 16 for more information.
13. Keep RE = 0 to prevent the device from entering SHDN.
14. The RE signal high time must be short enough (typically <100ns) to prevent the device from entering SHDN.
15. Transceivers (except on the ISL31491E) are put into shutdown by bringing RE high and DE low. If the inputs are in this state
16. Keep RE = VCC, and set the DE signal low time >600ns to ensure that the device enters SHDN.
17. Set the RE signal high time >600ns to ensure that the device enters SHDN.
18. Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise specified. Temperature limits established
19. Tested according to TIA/EIA-485-A, Section 4.2.6 (±80V for 15μs at a 1% duty cycle).
20. Does not apply to the ISL31491E.
21. See “Caution” statement below the “Recommended Operating Conditions” section on page 6.

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 “Low Power Shutdown Mode” on page 16.
