TL16C554AIFNR TI UART IC | 68-PLCC (24.23X24.23) | 4-Ch, 16B FIFO

Product Overview

The TL16C554AIFNR is a quad universal asynchronous receiver/transmitter (UART) from Texas Instruments, designed for serial data communication. It integrates four independent UART channels in a single 68-pin PLCC package, each with a 16-byte FIFO to reduce CPU overhead. Operating from a single 5V supply, it supports data rates up to 1 Mbps and is compatible with the industry-standard 16C550 UART. This device is ideal for multiport serial interfaces in industrial, telecom, and embedded systems.
