• Description: (ISL3150E - ISL3158E) RS-485/RS-422 Transceivers
• Manufacturer: Intersil Corporation

Electrical Specifications
NOTES:
10. Keep RE = VCC, and set the DE signal low time >600ns to ensure that the device enters SHDN.
12. Guaranteed by characterization but not tested.
13. See Figure 8 for more information, and for performance over temperature.

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. Keep RE = 0 to prevent the device from entering SHDN.
8. The RE signal high time must be short enough (typically <100ns) to prevent the device from entering SHDN.
