Overview

The ISL3331EVAL1Z evaluation board is RoHS compliant and provides a quick and easy method for evaluating the ISL3331 BiCMOS interface IC. The board was designed to allow the user to evaluate all the features available on the ISL3331 single port, 3.3V, ±15kV ESD protected, dual protocol (RS-232/RS-485) transceiver.

By changing jumper positions, the user can quickly set the board to evaluate any of the ISL3331's many modes and features, and the input states can also be set via jumpers.
