NS16C2752TVAX/NOPB

Overview

The NS16C2752TVAX/NOPB is a dual universal asynchronous receiver-transmitter (UART) interface 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 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 and draws a typical operating current of 3 mA.

Feature Summary

• Dual-channel architecture providing independent serial communication paths
• Integrated 64-byte FIFO buffers for both transmission and reception to minimize CPU intervention
• High-speed serial data transfer capability supporting baud rates up to 5 Mb/s
• Wide operating voltage compatibility ranging from 2.97 V to 5.5 V

Applications

• Industrial automation systems requiring reliable serial communication
• Embedded control units with multiple peripheral interfaces
• Data acquisition systems utilizing high-speed UART links

Procurement Notes

Verify the exact suffix against official Texas Instruments documentation to confirm package type and tape/reel specifications. Ensure the ordering part number matches the required moisture sensitivity level and RoHS compliance status for your manufacturing process. Cross-reference the manufacturer's latest datasheet to validate pinout configurations and electrical characteristics before finalizing procurement orders.

Selection Notes

Select this component when dual independent UART channels with substantial FIFO buffering are required. The wide voltage range supports systems operating between 3.3 V and 5 V logic levels. Consider the 48-pin TQFP package constraints for PCB layout. Verify that the 5 Mb/s maximum data rate meets the specific throughput requirements of the target application interface.

Part Context

This part belongs to the NS16C family of UART controllers, designed as pin-and-function compatible replacements for legacy 16C550/16C650 devices but with enhanced FIFO capabilities. The 'NOPB' suffix indicates lead-free construction and RoHS compliance. The 'TVAX' designation typically specifies the 48-pin TQFP package variant with specific tape and reel packaging for automated assembly processes.

Replacement Considerations

Direct functional substitutes include the NS16C2552 and NS16C4550 series from Texas Instruments, which offer similar dual-channel architectures. Verify pin compatibility and FIFO depth differences when migrating to these alternatives. Ensure that any replacement maintains support for the required baud rates and voltage operating ranges.
