The CA-IS3082W is a 16-pin SOIC16-WB(W) RoHS integrated circuit (IC) produced by Chipanalog. It is an RS-485/RS-422 Serial Communication Interface (SCI) IC that allows simple and reliable bi-directional communication to PCs and other devices. It is designed for high-speed, long-distance, point-to-point, point-to-multipoint, and multidrop applications. It features a 4-byte Rx/Tx FIFO, increased receive speed up to 500 kbps when using 4-wire differential mode, and improved EMI performance. The IC has a built-in transformer driver to provide a robust, noise-free interface to the outside world. The industry standard Pinouts ensure that the IC is compatible with all popular RS-485/RS-422 receivers.
