Home > Brand > TI > The TI ISO3086DWR interface isolator And a half-duplex RS-485 transceiver

The TI brand line of ISO3086DWR devices is isolated with all-duplex differential line drives and receiver, and this “device” is ideal for long transmission lines as the ground circuit is disconnected to allow for a larger common-mode voltage range.

The symmetric, symmetric isolation gate of the device has been tested to provide a 2,500 VRMS 60-second isolation interface between the bus transceiver and the logic level according to the UL1577 standard. Any wired input/output may be affected by electrical noise transients from a variety of sources. If in these words the noise transients have sufficient amplitude and duration, they may damage the transceivers and/or nearby sensitive circuits. This isolation These devices can significantly improve protection and reduce the risk of damage to expensive control circuits.

The ISO3086DWR device is certified to operate in the 40C to + 85C range.
