ISO308x Isolated 5-V Full- and Half-Duplex RS-485 Transceivers
The ISO3080 and ISO3086 devices are isolated fullduplex differential line drivers and receivers while the ISO3082 and ISO3088 devices are isolated halfduplex 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 2500 VRMS of isolation for 60 s 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. These isolated devices can significantly increase protection and reduce the risk of damage to expensive control circuiThe ISO3080, ISO3082, ISO3086, and ISO3088 device are qualified for use from –40°C to +85°C.
