Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix CN against official MaxLinear documentation to confirm the commercial temperature grade (0°C to 70°C) versus the extended grade. Ensure the tape and reel packaging matches production requirements. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm current active status and availability before finalizing procurement plans.

Drivers, Receivers, Transceivers Selection Notes

Select this component when full-duplex operation is required for RS-485 applications. Compare the 10 Mbps speed and 70 mV hysteresis against other models like the SP490EEN-L/TR which may offer different temperature ranges or packaging options. Confirm that the 8-pin SOIC footprint fits the design constraints and that the 4.75 V to 5.25 V supply voltage aligns with the system power architecture.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MaxLinear SP490 series of RS-485 interface ICs. It shares the core full-duplex functionality with variants such as the SP490EN-L and SP490EEN-L/TR. The primary distinction lies in the specific temperature rating and packaging configuration indicated by the suffix, allowing designers to choose based on environmental and manufacturing needs.

Drivers, Receivers, Transceivers Replacement Considerations

The SP490EEN-L/TR serves as a direct functional substitute within the same product family, offering identical electrical specifications but potentially differing in temperature range or package type. Verify pin compatibility and thermal characteristics before swapping.
