TL16C554AFNR TI UART Quad | 68-PLCC (24.23X24.23) | 1.5Mbps, 16B FIFO

Product Overview

The TL16C554AFNR is a quad universal asynchronous receiver/transmitter (UART) from Texas Instruments, designed for high-performance serial communication. Housed in a 68-pin PLCC package (24.23x24.23 mm), it integrates four independent UART channels, each capable of data rates up to 1.5 Mbps. With 16-byte FIFOs per channel, it reduces CPU overhead and enables efficient data handling in multi-port applications. The device operates from a single 5V supply and is compatible with industry-standard 16C550 UARTs, offering enhanced features for industrial and communication systems.
