TL16C554APN TI Quad UART | 80-LQFP (12x12) | 1.5Mbps, 5V

Product Overview

The TL16C554APN is a quad universal asynchronous receiver/transmitter (UART) from Texas Instruments, designed for high-performance serial communication. It integrates four independent UART channels in a single 80-pin LQFP package, each capable of data rates up to 1.5 Mbps. The device operates from a 5V supply and is compatible with 3.3V logic via selectable I/O voltage. It features 16-byte FIFOs per channel to reduce CPU overhead, making it ideal for multi-port serial applications in industrial, telecom, and embedded systems.
