Electrical Specifications
NOTES:
10. Keep RE = VCC, and set the DE signal low time >600ns to ensure that the device enters SHDN.
12. Does not apply to the ISL83071E and ISL83077E.
13. Δt
14. ISL83070E - ISL83075E only.
15. V
16. Limits established by characterization and are not production tested.
17. If the Tx or Rx enable function isn’t needed, connect the enable pin to the appropriate supply (see “Pin Descriptions” table) through a 1kΩ to 3kΩ
18. Parts are 100% tested at +25°C. Full temperature limits are guaranteed by bench and tester characterization.
11. Set the RE signal high time >600ns to ensure that the device enters SHDN.

4. All currents into device pins are positive; all currents out of device pins are negative. All voltages are referenced to device ground unless otherwise
5. Supply current specification is valid for loaded drivers when DE = 0V.
6. Applies to peak current. See “Typical Performance Curves” for more information.
7. When testing devices with the shutdown feature, keep RE = 0 to prevent the device from entering SHDN.
8. When testing devices with the shutdown feature, the RE signal high time must be short enough (typically <100ns) to prevent the device from
9. Versions with a shutdown feature are put into shutdown by bringing RE high and DE low. If the inputs are in this state for less than 50ns, the parts
