Electrical Specifications
Boldface limits apply over the operating temperature range, -40°C to +85°C.
NOTES:
10. The RE signal high time must be short enough (typically <100ns) to prevent the device from entering SHDN.
11. Transceivers are put into shutdown by bringing RE high and DE low. If the inputs are in this state for less than 60ns, the parts are guaranteed not to
12. Keep RE = V
13. Set the RE signal high time >600ns to ensure that the device enters SHDN.
14. Compliance to data sheet limits is assured by one or more methods: production test, characterization and/or design.
15. Tested according to TIA/EIA-485-A, Section 4.2.6 (±80V for 15µs at a 1% duty cycle).
16. See “Caution” statement below the “Latch-up (Tested per JESD78, Level 2, Class A) +125°C” section on page 5.
RECEIVER SWITCHING CHARACTERISTICS (15Mbps Versions; ISL32496E, ISL32498E)
6. All currents into device pins are positive; all currents out of device pins are negative. All voltages are referenced to device ground unless otherwise
7. Supply current specification is valid for loaded drivers when DE = 0V.
8. Applies to peak current. See “Typical Performance Curves” beginning on page 14 for more information.
9. Keep RE = 0 to prevent the device from entering SHDN.
