ISL32457EIUZ

The RS-485 bus pins in the ISL32450E through ISL32457E transceivers have ±15kV ESD protection.

The cable invert function in the ISL3245 transceiver allows for the reversal of the polarity of the Rx and Tx bus pins in case the cable is misconnected during installation. This function is beneficial in large node count RS-485 networks where some cable data lines may be wired backwards, leading to communication issues. By using the cable invert function, technicians can easily correct the miswiring without the need to rewire the connector, saving time and effort. The ISL3245 transceiver's cable invert function ensures proper communication even in situations where the cable connections are swapped, maintaining the integrity of the data transmission .

The common mode voltage range for the ISL32450E through ISL32457E transceivers is up to ±20V, exceeding the RS-485 requirement.
