Additional Details

The ISL8488IP features a robust driver output capable of driving heavily loaded cables. It also includes a receiver with high input impedance, minimizing load on the bus. The transceiver's driver output is protected against short circuits and thermal overload. The device operates over a wide industrial temperature range. The half-duplex operation allows for data transmission in both directions, but only one direction at a time.
