NOTES:
8. Compliance to data sheet limits is assured by one or more methods: production test, characterization and/or design.
9. Currents into device pins are positive; currents out of device pins are negative. Voltages are referenced to ground unless otherwise specified.
10. The ISL32611E enters SHDN whenever RE switches high, and the ISL32612E enters SHDN whenever RE switches low.
11. Devices meeting these limits are denoted as “1/8 unit load (1/8 UL)” transceivers. The RS-485 standard allows up to 32 Unit Loads on the bus, so
there can be 256 1/8 UL devices on a bus.
12. Not applicable to the ISL32610E.
