NS16C2752TVS/NOPB

Overview

The NS16C2752TVS/NOPB is a dual universal asynchronous receiver/transmitter (UART) integrated circuit manufactured by Texas Instruments. It features two independent UART channels, each equipped with a 64-byte FIFO buffer to enhance data throughput and reduce processor overhead. The device supports data rates up to 5 Mb/s and operates within a supply voltage range of 2.97 V to 5.5 V. It is housed in a 48-pin TQFP package suitable for surface-mount applications. The component functions across an industrial temperature range from -40°C to +85°C, with a typical operating supply current of 3 mA.

Feature Summary

• Dual-channel architecture with independent 64-byte FIFO buffers for each UART interface
• Supports high-speed serial communication with data rates reaching 5 Mb/s
• Compatible with standard logic levels via 5 V-tolerant I/O pins

Applications

• Industrial control systems requiring multiple serial communication ports
• Embedded systems needing reliable asynchronous data transfer
• Telecommunications equipment utilizing UART interfaces

Procurement Notes

Verify the complete part number including the NOPB suffix to ensure lead-free compliance and specific packaging configuration. Confirm that the TQFP-48 package dimensions align with your PCB footprint requirements. Check for moisture sensitivity level ratings if reflow soldering processes are involved. Ensure supply voltage constraints match your system design before procurement.

Selection Notes

Select this component when dual independent UART channels with substantial buffering are required. The 64-byte FIFOs help manage data flow efficiently in high-throughput scenarios. Verify that the 5.5 V maximum supply voltage fits your power domain. Consider the TQFP-48 package size relative to available board space compared to smaller alternatives.

Part Context

This part belongs to the NS16C2752 family of dual UART controllers. It serves as a robust solution for applications demanding multiple serial connections without excessive pin counts. The integration of large FIFOs distinguishes it from basic UART controllers, offering improved performance in interrupt-driven or DMA-based systems.

Replacement Considerations

Direct replacements must maintain dual UART functionality with similar FIFO depths and voltage tolerances. Verify pin compatibility if substituting within the same package type. Cross-reference datasheets for electrical characteristics to ensure seamless integration into existing designs.
