UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the complete part number including the suffix 'RG4' to ensure RoHS compliance and lead-free status. Confirm the package type is 32-VFQFN (5x5 mm) with exposed pad for proper PCB footprint design. Check moisture sensitivity level (MSL 3) requirements for storage and reflow soldering profiles. Ensure the supplier provides original manufacturer documentation to validate authenticity and traceability.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when dual UART functionality with 64-byte FIFOs is required in a compact surface-mount package. Consider the 1.62 V to 5.5 V supply range for compatibility with both 3.3 V and 5 V logic systems. Evaluate the 3 Mbps maximum data rate against application bandwidth needs. Compare pinout and thermal characteristics with alternative packages if space constraints differ.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the TL16C752 family of dual UART ICs from Texas Instruments. It is an enhanced version of the classic 16C750/16C752 designs, offering improved performance and modern packaging. The 'C' indicates commercial temperature range operation, while 'RHBR' specifies the 32-VFQFN reel-packaged variant. The 'G4' suffix denotes Green/RoHS-compliant manufacturing.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The TL16C752CIRHBR is listed as a parameter-equivalent substitute. Verify pin compatibility and electrical specifications before replacement. Ensure the alternative supports the same 64-byte FIFO depth and 3 Mbps data rate. Confirm package dimensions match the existing PCB layout.
