The ISO3086T is an isolated differential line transceiver with integrated oscillator outputs that provide the primary voltage for an isolation transformer. The device is a full-duplex differential line transceiver for RS-485 and RS-422 applications that can easily be configured for half-duplex operation by connecting pin 11 to pin 14, and pin 12 to pin 13.
These devices are ideal for long transmission lines since 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 4242 V PK of isolation for 1 minute per VDE 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 near-by 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 ISO3086T is specified for use from –40°C to 85°C.

ISO1176TEVM — ISO1176T 평가 모듈
This document describes the ISO1176T/35T/3086T Evaluation Module (EVM). It is used to evaluate the ISO1176T PROFIBUS Transceiver, the ISO35T RS-485 transceiver, or ISO3086T RS-485 Transceiver. Because the devices are similar transceivers, and the printed-circuit board is the same for all three (...)
