TL16C554APNR TI UART IC | 80-LQFP (12x12) | 4 Channels, 1.5Mbps

Product Overview

The TL16C554APNR from Texas Instruments is a quad universal asynchronous receiver/transmitter (UART) integrated circuit designed for serial communication. It features four independent UART channels in a compact 80-pin LQFP package (12x12 mm). Each channel supports data rates up to 1.5 Mbps and includes 16-byte FIFOs to reduce CPU overhead. The device operates from a 5V supply and is compatible with industry-standard 16C550 UARTs.
