SP335E - RS-232/RS-485/RS-422 TRANSCEIVER

General Description

The SP335 is an advanced multiprotocol transceiver supporting RS-232, RS-485, and RS-422 serial standards.

Integrated cable termination and multiple configuration modes allow all three protocols to be used interchangeably over a single cable or connector with no additional switching components.

SP335E RS-232/RS-485/RS-422 TRANSCEIVER WITH INTERNAL TERMINATION August 2017 GENERAL DESCRIPTION The SP335 is an advanced multiprotocol transceiver supporting RS-232, RS-485, and RS-422 serial standards. Integrated cable termination and multiple 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/RS-232 mode pin selects RS-485 mode when high, and RS-232 mode when low. In RS-485 mode, the TERM pin enables the differential 120 termination, and the HALF/FULL pin configures the transceiver as either half or full duplex. The high speed drivers operate up to 20Mbps in RS485/422 modes, and up to 1Mbps in RS-232 mode.
