The ISO3086DW is an isolated full-duplex RS-485 differential Line Transceiver ideal for long transmission lines because the ground loop is broken to allow for a much larger common-mode voltage range. The symmetrical isolation barrier of the device is tested to provide 2500Vrms of isolation for 60s per UL 1577 between the bus-line transceiver and the logic-level interface. Any cabled I/O can be subjected to electrical noise transients from various sources. This noise transient can cause damage to the transceiver and/or nearby sensitive circuitry if they are of sufficient magnitude and duration. This isolated device can significantly increase protection and reduce the risk of damage to expensive control circuits.
Thermal shutdown protection
16pF Typical low bus capacitance
50kV/µs Typical transient immunity
Fail-safe receiver for bus open, short or idle
Meets or exceeds TIA/EIA RS-485 requirements
Green product and no Sb/Br
This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
