The SP336 is a programmable RS-232 and/or RS-485/RS-422 transceivers. The SP336 contains four drivers and four receivers when selected in RS-232 mode; and two drivers and two receivers when selected in RS-485 mode. In addition, it may be configured for RS-232 and RS-485/RS-422 mix mode configuration.
The RS-232 transceivers can typically operate at 250kbps or 1Mbps while adhering to the RS-232 specifications. The RS-485/RS-422 transceivers can operate at 250kbps and 10Mbps while adhering to the RS-485/RS-422 specifications. The slew rate control pin minimizes problems with reflections on long and un-terminated cables. The RS-485/422 and RS-232 drivers and receivers can be disabled (High-Z output) by the three mode select pins.

07/17/2023 | In 2023, MaxLinear will be converting all shipping labels for the parts noted from an EXAR format to MaxLinear’s label. During this transition customers may receive either label. This change affects only shipping and packing labels. This change will not affect the part number, part marking, manufacturing process or manufacturing sites. Only work in progress material will be converted. Existing inventory from MaxLinear’s warehouse, channel sales, distributor, and such, will not be converted. Hence, customers may experience receiving mixed shipments with both Exar and MaxLinear labels for some period until existing inventory of old labels is eventually cleared out. Situation is product to product with no predictable way to determine when all old labels will be exhausted. No change to product form, fit, function and reliability. ADDENDUM A: Fixed MBB label logo for DX204001 to MaxLinear logo. ADDENDUM B: Replaced ‘All other affected products outer box label’ with clearer pictures. Corrected Date Issued (from original PCN) issue date +90 days to August 30, 2023. | PCN & PDN Download |

For RS-232 it is 50 feet (15 meters), or the cable length equal to a capacitance of 2500 pF, at a maximum transmission rate of 19.2kbps. When we reduce the baud rate, it allows for longer cable length. For Example:
Baud Rate (bps) | Maximum RS-232 Cable Length (ft) |
19200 | 50 |
9600 | 500 |
4800 | 1000 |
2400 | 3000 |

How to Design a Multiprotocol System using Only 1 Connector
Industrial networks support multiple serial interfaces such as RS-485 and RS-232. Using a multiprotocol transceiver enables industrial equipment to support both protocols using only one connector. Enabling both smaller and lower cost equipment designs. This video describes how to design multiprotocol systems using only one connector.
