General Description

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.
