Low-Cost Isolated RS-485 Transceiver Evaluation Board

The ISL32704EVAL1Z board enables the evaluation of the ISL32704E isolated, half-duplex RS-485 transceiver in a typical bus node application, used in isolated industrial networks.

The ISL32704E is a galvanically isolated, differential bus transceiver designed for bidirectional data transmission and meeting the RS-485 and RS-422 standards for balanced communication. Each of the bus terminals, A and B, is protected against ±15kV ESD strikes without latch-up.

The device uses giant magnetoresistance (GMR) as isolation technology. A unique ceramic/polymer composite barrier provides excellent isolation and virtually unlimited barrier life.
