TL16C754BFN

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The TL16C754BFN 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 asynchronous serial communication protocols with a maximum data transmission rate of 3 Mbps. It operates within a supply voltage range of 2.7 V to 5.5 V and utilizes a 68-pin Plastic Leaded Chip Carrier (PLCC) package. Key functional parameters include an 8-bit external data bus width, 3-bit address bus width, and a maximum clock frequency of 50 MHz.

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific suffix 'BFN' against the manufacturer's current datasheet to confirm pinout compatibility and operational temperature range. Ensure the component meets RoHS compliance requirements if mandated by your assembly standards. Cross-reference the part number with official Texas Instruments documentation to validate availability status and any recent product change notices affecting this specific variant.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select the TL16C754BFN when a design requires four distinct UART interfaces with substantial buffering capacity. The 64-byte FIFOs are suitable for applications with bursty data traffic to prevent overflow. Consider the PLCC-68 package constraints regarding PCB space and thermal management. Compare against single-channel alternatives if fewer ports are sufficient to optimize cost and board area.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This component belongs to the TL16C75x family of quad UARTs, which are widely used in embedded systems for serial communication. It serves as a direct replacement for older Intel 16C754 equivalents, offering improved performance through larger FIFOs and lower power consumption modes. The device is designed for robust operation in industrial environments, providing reliable data integrity over serial links.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The TL16C754BPNR is a documented alternative from Texas Instruments, featuring identical functionality but housed in an 80-LQFP package. Verify pin-to-pin compatibility if substituting into existing footprints, as the package dimensions differ significantly between PLCC and LQFP formats.
