This device has robust drivers and receivers for demanding industrial applications. The bus pins are robust to ESD events, with high levels of protection to Human-Body Model, Air-Gap Discharge, and Contact Discharge specifications.

The device combines a differential driver and a differential receiver, which operate from a single 5-V power supply. The driver differential outputs and the receiver differential inputs are connected internally to form a bus port suitable for half-duplex (two-wire bus) communication. The device features a wide common-mode voltage range making the device suitable for multi-point applications over long cable runs. The device is characterized from –40°C to 85°C.

TIDA-00527 — RS-485 匯流排供電參考設計

此設計展示了匯流排供電的 RS-485 應用的實作,並允許評估適合 DC 電源的不同濾波器。這樣可以節省單獨電源線佈線的成本和空間。

THVD8000 可實現利用開關鍵調變而透過電源線傳輸 RS-485 訊號的新方法。THVD8000 整合調變與解調電路,可提高傳輸基頻資料的頻率內容。這可簡化 DC 與 AC 耦合,以及與標準通用非同步接收器-發射器(通常用於 RS-485)的系統端介面,無需任何特殊編碼,在低資料速率應用中相當實用。這種升級方法適用於 DC 和 AC 電源,無需在微控制器中進行特殊編碼。
