The ISO1176T is an isolated differential line transceiver with integrated oscillator outputs that provide the primary voltage for an isolation transformer. The device is ideal for long transmission lines because the ground loop is broken to allow the device to operate with a much larger common-mode voltage range.
The symmetrical isolation barrier of each device is tested to provide 4242VPK of isolation per VDE for 60 seconds between the line transceiver and the logic-level interface.
The galvanically isolated differential bus transceiver is an integrated circuit designed for bi-directional data communication on multipoint bus-transmission lines. The transceiver combines a galvanically isolated differential line driver and differential input line receiver. The driver has an active-high enable with isolated enable-state output on the ISODE pin (pin 10) to facilitate direction control. The driver differential outputs and the receiver differential inputs connect internally to form a differential input/output (I/O) bus port that is designed to offer minimum loading to the bus whenever the driver is disabled or VCC2 = 0.
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 ISO1176T can significantly reduce the risk of data corruption and damage to expensive control circuits.
The device is characterized for operation over the ambient temperature range of 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。
