TL16C2550RHB

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The TL16C2550RHB is a dual universal asynchronous receiver/transmitter manufactured by Texas Instruments. It operates within a supply voltage range of 1.8V to 5.5V and supports data rates up to 1.5 Mb/s. The device integrates two independent UART channels, each equipped with a 16-byte FIFO for both transmit and receive operations. It utilizes a 32-pin VQFN package suitable for surface mount applications. The component functions across an industrial temperature range from -40°C to +85°C and draws approximately 7.5 mA during operation.
