Universal Asynchronous Receiver Transmitters

TL16C554FN Description

The TL16C554FN from Texas Instruments is a high-performance quad-channel Universal Asynchronous Receiver Transmitter (UART) designed for advanced serial communication applications. Housed in a 68-PLCC package, this surface-mount IC operates within a 4.75V to 5.25V supply range and delivers a maximum data rate of 1Mbps, making it suitable for high-speed data transmission. With 16-byte FIFOs per channel, it efficiently manages data flow, reducing CPU overhead and improving system performance. The device is RoHS3 compliant, adheres to EAR99 export controls, and features a Moisture Sensitivity Level (MSL) of 3 (168 Hours).

TL16C554FN Features

• Quad-Channel UART: Four independent UART channels (QUART) for multi-port communication.
• 16-Byte FIFOs: Minimizes CPU interrupts and enhances data throughput.
• Modem Control: Includes modem control signals (RTS, CTS, DSR, DTR, CD, RI) for robust peripheral interfacing.
• False Start Bit Detection: Improves data integrity by detecting erroneous start bits.
• 1Mbps Data Rate: Supports high-speed serial communication.
• Surface-Mount Design: 68-PLCC package for compact PCB integration.
• Wide Operating Voltage (4.75V–5.25V): Ensures compatibility with standard 5V systems.
• REACH Unaffected & RoHS3 Compliant: Meets environmental and regulatory standards.

TL16C554FN Applications
