SP338EER1-L/TR

Drivers, Receivers, Transceivers Overview

The SP338EER1-L/TR is a multiprotocol transceiver manufactured by MaxLinear, Inc., housed in a 40-lead QFN (6x6 mm) package. It integrates three drivers and five receivers to support RS-232, RS-422, and RS-485 communication standards simultaneously. The device operates on dual power supplies of 3.3V and 5V, ensuring compatibility with various logic levels. It supports data rates up to 1Mbps with full-duplex transmission capability. The receiver input features a 300mV hysteresis for noise immunity. The component is rated for an extended industrial operating temperature range from -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Supports simultaneous operation across RS-232, RS-422, and RS-485 protocols within a single integrated circuit.
• Integrates multiple driver and receiver channels to reduce board space and system complexity.
• Provides enhanced noise immunity through specified receiver hysteresis characteristics.

Drivers, Receivers, Transceivers Applications

• Industrial automation systems requiring mixed protocol connectivity
• Embedded control units with diverse serial communication needs
• Data acquisition modules interfacing with multiple sensor types

Drivers, Receivers, Transceivers Procurement Notes

Verify the manufacturer designation carefully, as listings may attribute this part to Exar Corporation due to historical corporate acquisitions. Confirm the specific suffix indicates the tape-and-reel packaging variant. Ensure the source document explicitly identifies the component as a transceiver rather than an evaluation board or development tool associated with similar model numbers.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a design requires concurrent support for RS-232, RS-422, and RS-485 interfaces without using separate discrete chips. The 40-QFN package is suitable for compact PCB layouts. Verify that the required data rate does not exceed 1Mbps and that the application environment falls within the specified -40°C to +85°C temperature range.

Drivers, Receivers, Transceivers Part Context

This part belongs to the SP338E series of multiprotocol transceivers. It shares functional similarities with the SP339E series but differs in supported data rates and temperature specifications. The 'L' suffix typically denotes lead-free compliance, while '/TR' indicates reel packaging. It serves as a consolidated solution for legacy serial interface integration in modern embedded hardware.

Drivers, Receivers, Transceivers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. The SP338ECR1-L is listed as a discontinued alternative within the same family. Designers should verify pinout and electrical parameter compatibility before considering any cross-reference components.
