SP336E 3.3V / 5V PROGRAMMABLE RS-232/RS-485/RS-422 SERIAL TRANSCEIVER May 11, 2022 Rev. 1.1.1 GENERAL DESCRIPTION The SP336E is a monolithic serial multi-transceiver device that contains both RS-232 and RS-485/RS422 line drivers and receivers. The configuration of the SP336E can be reconfigured into eight operating modes including RS-232 only (4TX/4RX), RS-485/ RS-422 only (2TX/2RX) full or half duplex, two RS232/RS-485 mixed modes. two shutdown modes and a diagnostic loop-back mode. Modes may be selected at any time by changing the logic state of the three MODE pins. The device can implement a dualmode serial port, mixed mode ports or as an interface signal translator. The MaxLinear charge pumps deliver true RS-232 driver output voltages from a single power supply at either 3.3V or 5V.
