RS-485 Transceiver Tutorial
With the plethora of transceivers on the market, it can be challenging to pick the best, most cost effective device for your application. This white paper guides you through the choices and weighs key design considerations to help you pick the right transceiver. First, we'll review the most typical RS-485 ICs and explore the most common design considerations. Then, we'll examine electrostatic discharge (ESD) protection and compare the Human Body Model (HBM) and IEC61000-4-2 (IEC) standards. Finally, we'll discuss over voltage protection (OVP) and provide a snapshot of very high-speed transceivers (above 25Mbps) where data skew is critical.
