Exar SP338E Multiprotocol Serial Transceivers & Eval Board
Exar SP338E Multiprotocol Serial Transceivers are advanced multiprotocol transceivers supporting RS-232, RS-485, and RS-422 serial standards in a 40 pin QFN package. Integrated cable termination and four configuration modes allow all three protocols to be used interchangeably over a single cable or connector with no additional switching components. Full operation of the Exar SP338E Multiprotocol Serial Transceivers requires only four external charge pump capacitors. The RS-485/RS-422 modes feature up to two drivers and four receivers (2TX/4RX) in half, full, and mixed duplex configurations. The RS-232 mode (3TX/5RX) provides full support of all eight signals commonly used with the DB9 RS-232 connector. An Exar SP338E Multiprotocol Serial Transceiver Evaluation Board is also available.
