TL16C554APNR

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The TL16C554APNR is a quad universal asynchronous receiver/transmitter (UART) integrated circuit manufactured by Texas Instruments. It integrates four independent UART channels, each equipped with a 16-byte first-in-first-out (FIFO) buffer to enhance data throughput and reduce processor overhead. The device operates within a supply voltage range of 3V to 5.25V and supports maximum clock frequencies up to 16 MHz. It features an 80-pin Low-Profile Quad Flat Package (LQFP) with dimensions of 12mm x 12mm. The component is designed for asynchronous serial communication protocols, supporting data rates up to 1 Mbps.
