Single-Bus RS485/RS232 Multiprotocol Transceiver with Switchable Termination

DESCRIPTION The LTC?2873 is a robust pin-configurable multiprotocol transceiver that supports RS232, RS485, and RS422 protocols while operating on a single 3V to 5.5V supply. The LTC2873 can be configured as a half-duplex RS485 transceiver or as an RS232 transceiver using the same two bus pins.
