TL16C552AIFNG4

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The TL16C552AIFNG4 is a dual-channel Universal Asynchronous Receiver/Transmitter (UART) manufactured by Texas Instruments. It integrates two independent UARTs within a single 68-pin Plastic Leadless Chip Carrier (PLCC) package. Each channel features 16-byte transmit and receive FIFOs to enhance data throughput and reduce processor intervention. The device supports asynchronous communication protocols with a maximum data rate of 1 MBd. It operates on a typical supply voltage of 5 V and functions reliably across an industrial temperature range from -40 °C to +85 °C. The component measures 24.23 mm in length and width, with a height of 4.06 mm.
