TL16C754BPNR

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The TL16C754BPNR is a quad universal asynchronous receiver/transmitter (UART) integrated circuit manufactured by Texas Instruments. It features four independent UART channels, each equipped with a 64-byte FIFO buffer to enhance data throughput and reduce processor intervention. The device supports maximum data rates of 3 Mbps and operates within a supply voltage range of 2.7 V to 5.5 V. It is housed in an 80-LQFP package measuring 12x12 mm. Key functional attributes include automatic flow control, modem control signals, and false start bit detection. The component complies with RoHS3 standards and has a moisture sensitivity level of MSL 3.

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required packaging and temperature grades. Confirm that the 80-LQFP footprint matches the target PCB design. Check for any recent product change notices regarding manufacturing location or material composition updates before finalizing procurement plans.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when four independent UART channels with substantial 64-byte buffering are required. Ensure the system power supply remains within the 2.7 V to 5.5 V operating range. Verify that the 80-LQFP package dimensions fit the available board space. Consider the 3 Mbps speed limit when designing for high-baud-rate applications compared to lower-capacity alternatives.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the TL16C754 family of quad UARTs from Texas Instruments. It serves as a higher-performance alternative to the TL16C554 series, which typically offers smaller 16-byte FIFOs. The 'PNR' suffix indicates a specific tape-and-reel packaging variant suitable for automated surface-mount assembly processes.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The TL16C754FN is a pin-compatible alternative in a 68-PLCC package. For designs requiring smaller FIFOs, the TL16C554APNR may serve as a functional substitute if channel count and interface timing remain compatible with the existing system architecture.
