Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'L/TR' indicates tape-and-reel packaging when sourcing components. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets before finalizing procurement plans.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring full-duplex RS-485 connectivity. Ensure the design accommodates the 14-pin SOIC footprint and validates power supply stability within the specified 4.75V to 5.25V operating window for optimal signal integrity.

Drivers, Receivers, Transceivers Part Context

This part belongs to the SP491 series of line transceivers manufactured by MaxLinear. It serves as a serial interface solution for differential data transmission, distinct from half-duplex variants like the SP485 series which utilize different pin configurations.

Drivers, Receivers, Transceivers Replacement Considerations

Cross-reference with SP491EEN-L/TR for identical electrical specifications but potential packaging differences. Verify compatibility with legacy Exar or Sipex versions of the SP491EN-L/TR regarding pinout and functional equivalence.
