Drivers, Receivers, Transceivers Procurement Notes

Verify the specific manufacturer lot code and date code upon receipt to ensure authenticity. Confirm that the received components match the SP490EEN-L/TR designation exactly. Check for physical damage to the SOIC-8 package leads. Ensure storage conditions adhere to the specified moisture sensitivity level requirements before soldering.

Drivers, Receivers, Transceivers Selection Notes

Select this component when full-duplex RS-485 connectivity is required in space-constrained designs. The SOIC-8 package offers a smaller footprint compared to larger alternatives. Consider the 10 Mbps speed limit and 5V supply requirement during system architecture planning. Verify 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 MaxLinear SP490E series of line transceivers. It serves as a single-driver, single-receiver solution for differential data transmission. The series is designed to replace legacy RS-485 components while offering improved performance metrics such as higher data rates and better noise tolerance in harsh electrical environments.

Drivers, Receivers, Transceivers Replacement Considerations

Cross-reference with other MaxLinear SP490 variants or equivalent industry-standard RS-485 transceivers. Verify pinout compatibility and electrical specifications before substitution. Ensure the alternative component meets the same voltage and temperature requirements.
