PC16550DVX TI UART IC | 44-PLCC (16.58X16.58) | 1.5Mbps, 5V

Product Overview

The PC16550DVX is a Universal Asynchronous Receiver/Transmitter (UART) integrated circuit from Texas Instruments (TI). It is designed to provide serial communication capabilities in a wide range of applications, offering high performance and reliability. Housed in a 44-pin PLCC package (16.58x16.58 mm), this device supports data rates up to 1.5 Mbps and operates at a supply voltage of 5V. The PC16550DVX is a direct upgrade to the industry-standard 16550 UART, featuring a 16-byte FIFO buffer that reduces CPU overhead and improves data throughput.
