Half-duplex RS485/RS422 transceiver at 20Mbps
The ISL83078EIBZA is a single-channel half-duplex transceiver supporting both RS422 and RS485 protocols. It operates at a data rate of 20Mbps, which is sufficient for high-speed fieldbus links such as Profibus or Modbus RTU at faster baud rates. Supply voltage range is 3V to 3.6V, so it runs directly from a 3.3V rail without a separate regulator. The 15 mV receiver hysteresis reduces noise-induced bit errors on long cable runs.
Industrial temperature grade and 8-SOIC footprint
The narrow SOIC pitch (1.27 mm) routes easily on two-layer boards.
Renesas lists the ISL83078EIBZA as Active. ROHS3 compliant.
