NOTES:
2. 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.
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 ISL83483, ISL83485, ISL83491, keep RE = 0 to prevent the device from entering SHDN.
6. When testing the ISL83483, ISL83485, ISL83491, the RE signal high time must be short enough (typically <100ns) to prevent the device from
entering SHDN.
7. The ISL83483, ISL83485, ISL83491 are put into shutdown by bringing RE high and DE low. If the inputs are in this state for less than 80ns, the
parts are guaranteed not to enter shutdown. If the inputs are in this state for at least 300ns, the parts are guaranteed to have entered shutdown.
See “Low-Power Shutdown Mode” section.
8. Keep RE = VCC, and set the DE signal low time >300ns to ensure that the device enters SHDN.
9. Set the RE signal high time >300ns to ensure that the device enters SHDN.
Electrical Specifications
Test Conditions: VCC = 3V to 3.6V; Unless Otherwise Specified. Typicals are at VCC = 3.3V, TA = 25oC,
