ISO3082DW, Изолированный приемопередатчик интерфейса RS485 [SO-16]

The ISO3080 and ISO3086 devices are isolated fullduplex differential line drivers and receivers while the ISO3082 and ISO3088 device are isolated half-duplex differential line transceivers for TIA/EIA 485/422 applications. These devices are 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. These noise transients 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.
