NS16C2752TVSX/NOPB

Overview

The NS16C2752TVSX/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 transmit and receive FIFO buffer to enhance data throughput and reduce CPU 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-lead TQFP package suitable for surface-mount applications. The component functions across an industrial temperature range from -40°C to +85°C and draws a typical operating current of 3 mA.

Feature Summary

• Dual-channel architecture with independent 64-byte FIFO buffers for each UART port
• High-speed serial communication capability supporting baud rates up to 5 Mb/s
• Wide operating voltage compatibility ranging from 2.97 V to 5.5 V
• Industrial-grade thermal performance spanning -40°C to +85°C

Applications

• Industrial automation systems requiring reliable serial communication
• Embedded control units needing multiple UART interfaces
• Telecommunications equipment utilizing high-speed data transfer
• Computer peripheral interface designs

Procurement Notes

Verify the specific suffix 'X' against official Texas Instruments documentation to confirm tape-and-reel packaging specifications. Ensure the NOPB designation confirms lead-free and RoHS compliance status as per current manufacturing standards. Cross-reference the full part number with authorized distributors to validate active status and availability constraints before procurement.

Selection Notes

Select this component when dual independent UART channels with substantial FIFO buffering are required. The wide voltage range allows flexibility in power supply design. Consider the TQFP-48 package dimensions for PCB layout constraints. Verify that the 5 Mb/s maximum data rate meets system timing requirements and that the operating temperature range aligns with the environmental conditions of the target application.

Part Context

This device belongs to the NS16C2752 family of dual UART controllers. It serves as a successor or variant to earlier single-channel UARTs, offering increased integration. The 'NOPB' suffix indicates non-plastic body or lead-free processing depending on specific TI nomenclature updates. It is designed for applications replacing legacy 16C550/552A equivalents with enhanced FIFO capabilities.

Replacement Considerations

Direct pin-compatible replacements may include other 16C2752 variants from Texas Instruments or compatible devices from other manufacturers offering dual UART functionality with similar FIFO sizes. Verify electrical characteristics and register compatibility before substitution.
