MaxLinear XR34350 Multiprotocol Transceiver

MaxLinear XR34350 Multiprotocol Transceiver supports the RS-232, RS-485, and RS-422 serial standards. This transceiver offers a single cable interchange for all three protocols. The XR34350 operates up to 1Mbps in RS-232 mode and up to 20Mbps in RS-422/RS-485 mode. The transceiver features 250kbps slew limiting to minimize Electromagnetic Interference (EMI). The XR34350 operates from a single power supply, either 3.3V or 5V, with a low idle current of 2mA in all modes.

The MaxLinear XR34350 Multiprotocol Transceiver is available in a compact QFN-40 package.
