The ISL83075EIBZA is a half-duplex RS-422/RS-485 transceiver from Renesas, rated for a data rate of 500 kbps. At this speed on a typical twisted-pair RS-485 bus, you can run cable lengths up to roughly 1200 metres before signal degradation eats the margin — the 15 mV receiver hysteresis gives you noise immunity on long drops in industrial environments.
Supply rail and temperature – fit check for the BOM
This part runs on a single 3.0 V to 3.6 V rail — a tight 3.3 V ±10 % supply. It is not a wide-input part; your board needs a clean 3.3 V bus already in place.
Package and rework – 8-SOIC narrow-body
No special bake-out required for MSL level (typical for this package class).
