Additional Details

The ISL3159EFUZ includes a robust driver output capable of driving heavily loaded cables. The fail-safe receiver inputs guarantee a known output state when the bus is idle or shorted. 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. The high ESD protection ensures reliable operation in environments with high levels of static electricity.
