UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the exact suffix 'FNG4' against official Texas Instruments documentation to confirm pinout, temperature range, and RoHS compliance status. Ensure the ordering part number matches the specific package variant required for your PCB design. Cross-reference with the latest datasheet revision to confirm any updates to electrical characteristics or mechanical dimensions before finalizing procurement.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when four independent UART interfaces are required in a single package. Consider the 16-byte FIFO depth for buffering requirements and the 1 Mbps speed limit for bandwidth needs. Verify that the 80-LQFP package fits your board space constraints. Ensure the system power supply falls within the 3V to 5.25V operating range for proper functionality.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

The TL16C554 series belongs to Texas Instruments' family of asynchronous communication elements. It is part of the broader TL16C55x lineup, which includes variants with different channel counts and FIFO sizes. This specific model provides a quad-channel solution, distinguishing it from dual-channel or single-channel counterparts in the same product family.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Check for direct replacements such as the TL16C554AIPN or TL16C554APNR, which share similar quad-channel specifications. Verify pin-to-pin compatibility and electrical parameter equivalence before substitution. Consult the manufacturer's replacement guide for any recommended upgrades or legacy component transitions.
