UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific suffix FNR against official datasheets to confirm tape-and-reel packaging and lead frame composition. Confirm RoHS compliance status through manufacturer documentation prior to integration. Ensure ESD protection measures are implemented during handling due to moisture sensitivity classification. Validate pinout compatibility with target PCB layout designs before finalizing procurement orders.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a single UART channel with hardware flow control is required in a PLCC-44 footprint. Compare against TL16C450FN for tube packaging alternatives if reel quantities are not needed. Evaluate TL16C550 variants if higher data rates or FIFO buffers are necessary for the application design requirements.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the TL16C45x family of asynchronous communication elements. It serves as a foundational interface component for legacy and industrial serial systems. The device complements other members like the TL16C451 and TL16C452, which offer parallel port extensions or dual-channel configurations respectively.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The TL16C450FN is a direct functional equivalent differing primarily in packaging format (tube versus reel). Verify pin-to-pin compatibility and electrical specifications before substitution.
