0 GENERAL DESCRIPTION The SP339B is an advanced multiprotocol transceiver 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 requires only four external charge pump capacitors.
The RS-485/422 modes feature one driver and one receiver (1TX/1RX) in both half and full duplex configurations.
The RS-232 mode (3TX/5RX) provides full support of all eight signals commonly used with th...
