Overview
The SC16C554DBIB64,157 is a 4-channel Universal Asynchronous Receiver and Transmitter (UART) produced by NXP USA Inc. This component is designed for serial data communications and is part of the SC16C554B/554DB family. It converts parallel data into serial data and vice versa, supporting serial data rates up to 5 Mbit/s. The device is fabricated using an advanced CMOS process, ensuring low power consumption and high-speed performance. It is pin compatible with the ST16C554 and TL16C554 and power-ups to be functionally equivalent to the 16C454, with additional enhanced features such as 16-byte receive and transmit FIFOs and four selectable FIFO trigger levels.
