SP339EER1-L from MaxLinear, Inc. is an active full-duplex transceiver for RS-232, RS-422, RS-485 serial interfaces. It integrates 3/5 driver/receiver channels, supports data rates up to 1Mbps, and operates from 3.3V, 5V.

Selection profile: Its full-duplex architecture uses separate transmit and receive signal paths; confirm the required four-wire topology during selection. This is a multiprotocol device covering RS-232, RS-422, RS-485, so mode selection and pin configuration should be confirmed for the intended interface. The 1Mbps data-rate rating, 3.3V, 5V supply range, and -40°C ~ 85°C operating range distinguish this orderable part in the catalog.

Package and ordering: SP339EER1-L is supplied in QFN-40; the source package designation is 40-QFN (6×6), with Tray packaging options listed for this orderable part. Confirm reel, tube, tray, or cut-tape requirements against the full manufacturer ordering code before purchase.

Use the linked datasheet to verify pinout, protection features, timing limits, termination requirements, and application-specific conditions. Availability, lead time, and order quantity require RFQ confirmation.
