ESD PERFORMANCE
RS-485 Pins (A/Y, B/Z) Human Body Model 25 - 15 - kV
All Other Pins 25 - >7- kV
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” on page 10 for more information.
5. When testing the ISL8483E, keep RE
= 0 to prevent the device from entering SHDN.
6. When testing the ISL8483E, the RE
signal high time must be short enough (typically <200ns) to prevent the device from entering SHDN.
7. The ISL8483E is put into shutdown by bringing RE
high and DE low. If the inputs are in this state for less than 50ns, 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 (ISL8483E Only)” on page 9.
8. Keep RE
= V
CC
, and set the DE signal low time >600ns to ensure that the device enters SHDN.
9. Set the RE
signal high time >600ns to ensure that the device enters SHDN.
10. Devices meeting these limits are denoted as “single unit load (1 UL)” transceivers. The RS-485 standard allows up to 32 Unit Loads on the bus.
11. Limits established by characterization and are not production tested
.
12. 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.
