Interfacing to the RX Pin of the Teridian 6511, 6513 and 6515


Due to its unique circuitry, the RX input functions differently than the other digital inputs on the Teridian 71M6511, 71M6511H, 71M6513, and 71M6515H family of single- and 3-phase energy-metering ICs. This application note explains what unique considerations apply when interfacing signals that exceed the 0 to 3.6V range to the RX pin. The article also describes the pin summary and considerations when connecting 5V-based circuitry to the RX pin. Read full article.
