TL16C554AFN TI UART IC | 68-PLCC (24.23x24.23) | 4-Ch, 1.5Mbps

Product Overview

The TL16C554AFN from Texas Instruments is a quad universal asynchronous receiver/transmitter (UART) integrated circuit designed for serial communication. It provides four independent UART channels in a single 68-pin PLCC package, making it ideal for applications requiring multiple serial ports. Each channel supports data rates up to 1.5 Mbps and includes 16-byte FIFOs to reduce CPU overhead. The device operates from a single 5V supply and is compatible with industry-standard 16C550 UARTs.
