TL16C552AFNRG4

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The TL16C552AFNRG4 is a dual-channel Universal Asynchronous Receiver/Transmitter (UART) integrated circuit manufactured by Texas Instruments. It features independent transmit and receive 16-byte FIFOs for each channel, supporting data rates up to 1 MBd. The device operates on a single 5 V supply voltage and includes an onboard 1.8432 MHz clock generator. It supports standard asynchronous protocols with programmable stop bits and parity options. The component is housed in a 68-pin PLCC package and is rated for operation within a temperature range of -40 °C to +85 °C.
