UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific suffix 'IVTR' against official MaxLinear documentation to confirm the tape-and-reel packaging configuration and industrial/commercial temperature grade. Ensure the order matches the exact part number to avoid discrepancies in pinout or electrical characteristics compared to tray-packaged variants. Cross-reference the datasheet revision date to confirm current design recommendations.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a design requires four distinct UART interfaces within a limited footprint. The 64-byte FIFO depth is suitable for applications needing moderate buffering without complex DMA controllers. Verify that the operating voltage aligns with the system's 3.3V or 5V logic levels and that the commercial temperature range meets the environmental requirements of the target application.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the XR16L series of UART interface ICs from MaxLinear, which focuses on providing multi-channel serial communication solutions. The series is characterized by its integration of multiple UARTs into single packages to simplify board design. The XR16L784 specifically targets applications needing quad-channel capability, distinguishing it from single or dual-channel counterparts in the same product family.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Direct substitutes include the XR16L784CV-F for tray packaging or the XR16L784IM-F if a different package variant is acceptable. Check for functional equivalents in the XR16M series for higher performance needs, though pin compatibility may vary. Always validate pinouts and electrical specs before swapping.
