ISL32435EIBZ

The RS-485 bus pins in the ISL32430E through ISL32437E transceivers have ±15kV ESD protection.

The purpose of the cable invert function in the ISL3243 transceiver is to simplify the task of correcting miswired nodes in large RS-485 networks. This function allows technicians to invert the polarity of the Rx input and Tx output pins by moving a jumper, enabling communication over the network without the need to rewire the connector, which can be time-consuming. The cable invert function ensures that even with reversed polarity, the Rx full fail-safe function is maintained, unlike competing devices that may deliver incorrect logic outputs in inverted mode.

The common mode voltage range for the ISL32430E through ISL32437E transceivers is up to ±15V, exceeding the RS-485 requirement. This makes this RS-485 family one of the more robust on the market.
