TL16C451FNR TI UART with FIFO | 68-PLCC (24.23X24.23) | 4-Ch, 1Mbps

Product Overview

The TL16C451FNR from Texas Instruments is a high-performance quad universal asynchronous receiver/transmitter (UART) designed for serial communication in industrial and embedded systems. Housed in a 68-pin PLCC package (24.23x24.23 mm), it integrates four independent UART channels with 16-byte FIFOs, supporting data rates up to 1 Mbps. The device operates from a single 5V supply and includes a programmable baud rate generator, modem control signals, and a versatile interrupt system. Its robust design ensures reliable data transfer in noise-prone environments, making it ideal for multi-port serial interfaces in networking, telecommunications, and industrial automation.
