NSi83085E/NSi83086E High Reliability Isolated Half and Full-Duplex RS-485 Transceivers Datasheet (EN) 1.1 Product Overview NSi83085E is a high reliability isolated half duplex RS-485 transceiver based on NOVOSENSE digital isolation technology, while NSi83086E is an isolated full duplex RS485 transceiver. Both devices are safety certified by UL1577 support 5kVrms insulation withstand voltages, while providing high electromagnetic immunity and low emissions at low power consumption. The Bus pins of NSi83085E/NSi83086E are protected from ±10kV system level ESD to GND2 on Bus side. These devices feature fail-safe circuitry, which guarantees a logic-high receiver output when the receiver inputs are open or shorted. The devices have a 1/8-unit-load receiver input impedance that allows up to 256 transceivers on the bus. The data rate of NSi83085E is 12Mbps. The device is slew limited to reduce EMI and reflections with improperly terminated transmission line. The data rate of NSi83086E is up to 16Mbps.
