The TRS3386E is a three-driver and two-receiver RS-232 interface device, with split supply pins for mixed-signal operations. All RS-232 inputs and outputs are protected to ±15 kV using the IEC 61000-4-2 Air-Gap Discharge method, ±8 kV using the IEC 61000-4-2 Contact Discharge method, and ±15 kV using the Human-Body Model.
The charge pump requires only four small 0.1-µF capacitors for operation from a 3.3-V supply. The TRS3386E is capable of running at data rates up to 250 kbps, while maintaining RS-232-compliant output levels.
The TRS3386E has a unique VL pin that allows operation in mixed-logic voltage systems. Both driver in (DIN) and receiver out (ROUT) logic levels are pin programmable through the VL pin. The TRS3386E is available in a space-saving thin shrink small-outline package (TSSOP).

TIDA-00225 — 適用於 BeagleBone Black 的資料集中器 Cape
此設計為使用 BeagleBone Black 平台的開發人員提供全新連線選項。此模組能讓開發人員搭配 TI 的電源線通訊 (PLC) 和射頻模組,輕鬆快速地開發智慧電網的主機應用程式。開發人員可輕易地為 BeagleBone Black 打造專屬 Cape,並開始使用 TI 的 G3-PLC、6LowPAN、PRIME、無線 M-Bus 或 ZigBee® 解決方案。
TIDA-00540 — RS-485 / RS-232 多協定收發器參考設計
此設計 (TIDA-00540) 允許透過 RS-485 或 RS-232 資料匯流排通訊,而無需每個匯流排單獨配線。 兩種不同類型的收發器共用資料線,並透過單一控制訊號決定要使用的通訊協定。
