UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific suffix IRHB against the official datasheet to confirm the VQFN-32 package and tape-and-reel or tray packaging details. Confirm RoHS compliance status through the manufacturer's current documentation. Check for any recent product discontinuation notices as availability may be limited. Ensure the ordering part number matches the required pin configuration and thermal characteristics.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when dual UART functionality is required in a compact surface-mount form factor. The wide voltage range makes it suitable for mixed-voltage systems. Consider the 16-byte FIFO depth for applications requiring moderate buffering without complex DMA controllers. Verify that the 1.5 Mb/s maximum speed meets the system's baud rate requirements.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the TL16C2550 series of dual UART interface ICs. It serves as a successor or alternative to legacy single-channel UARTs, offering increased integration density. The device is designed to replace older components like the ST16C2550 or SC16C2550 in existing designs while providing enhanced performance and lower power consumption.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Publicly confirmed substitutes include the TL16C2550IRHBR (same function, different packaging) and the TL16C2550IRHBRG4. Verify pin compatibility and electrical specifications before substitution.
