Product Overview

The ISO3082DW is an Isolated 5V Half-duplex RS-485 Transceiver, isolated full-duplex differential line driver and receiver while the ISO3082 and ISO3088 device is isolated half-duplex differential line transceivers for TIA/EIA 485/422 applications. This device is 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.
