The ISO35T 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 4242V_PK of isolation per VDE for 60s 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. The ISO35T can significantly reduce the risk of data corruption and damage to expensive control circuits.

The ISO35T is specified for use from –40°C to 85°C.

ISO1176TEVM — ISO1176T 评估模块

本文档介绍了 ISO1176T/35T/3086T 评估模块 (EVM)。它用于评估 ISO1176T PROFIBUS 收发器、ISO35T RS-485 收发器或 ISO3086T RS-485 收发器。由于这些器件是相似的收发器，并且三款 EVM 的印刷电路板相同，因此本手册可用于全部三款器件。

EVM 在充当电路板布局指南的同时，还可用于评估器件参数。该电路板允许通过 QuiteZone 连接器连接 50Ω 同轴电缆。它还为示波器探针提供了方便的连接点。为 DC 电源连接提供了香蕉插孔。这些功能为设计人员提供了评估和成功设计出最终产品所需的工具。
