Specifications

Description

The ISO3080 and ISO3086 devices are isolated full duplex differential line drivers and receivers while

the ISO3082 and ISO3088 devices 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 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 circuits. The

ISO3080, ISO3082, ISO3086, and ISO3088 device are qualified for use from –40°C to +85°C.
