NS16C2552TVAX/NOPB

Overview

The NS16C2552TVAX/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 16-byte transmit and receive FIFO buffer to enhance data throughput and reduce processor overhead. The device supports standard serial communication protocols including RS-232, RS-422, and RS-485. It operates within an industrial temperature range of -40°C to +85°C and is housed in a 48-pin TQFP package suitable for surface-mount assembly.

Feature Summary

• Dual independent UART channels with dedicated 16-byte FIFO buffers for efficient data handling
• Supports multiple serial communication standards including RS-232, RS-422, and RS-485
• Industrial-grade operational capability across extended temperature ranges

Applications

• Industrial automation systems requiring reliable serial communication
• Embedded control units utilizing multi-channel UART interfaces
• Data acquisition equipment needing buffered serial data transfer

Procurement Notes

Verify the specific suffix 'TVAX' against official Texas Instruments documentation to confirm pinout and electrical characteristics, as variations exist within the NS16C2552 family. Ensure the component meets RoHS compliance requirements for your target market. Confirm availability through authorized distributors, as lead times may vary based on production schedules.

Selection Notes

Select this component when dual UART functionality with hardware flow control and FIFO buffering is required. Compare against single-channel alternatives if only one interface is needed. Verify voltage levels and package constraints against the PCB layout. Consider the operating temperature range to ensure suitability for the intended environmental conditions.

Part Context

This part belongs to the NS16C2552 series of dual UART controllers from Texas Instruments. It serves as a high-performance alternative to legacy UART designs by integrating substantial FIFO memory. The series is designed for applications demanding robust serial connectivity in compact form factors.

Replacement Considerations

Check for direct pin-to-pin replacements within the TL16C2552 or NS16C550 families. Verify functional compatibility regarding register sets and timing parameters before substitution.
