DS3883AVX

Overview

The DS3883AVX is a BTL (Balanced Transmission Line) 9-bit data transceiver manufactured by National Semiconductor. It features an inverting configuration with one element containing nine bits per element. The device provides a 3-state output and is housed in a 44-QFP package measuring 10x10 mm. This component functions as a buffer, driver, receiver, and transceiver within interface IC applications.

Feature Summary

• Inverting transceiver architecture with balanced transmission line support
• Nine-bit data handling capability per element
• Three-state output functionality for bus isolation

Applications

• Balanced transmission line data communication
• Industrial interface circuits requiring signal inversion
• Embedded systems utilizing 9-bit data protocols

Procurement Notes

Verify the manufacturer designation, as National Semiconductor assets are managed by Texas Instruments. Confirm the specific suffix AVX corresponds to the required temperature range and packaging specifications. Ensure compatibility with existing system voltage levels and logic families before integration into the design.

Selection Notes

Select this component when a balanced transmission line interface with inverted logic is required. The 9-bit width suits specific legacy or specialized data formats. The 44-QFP package dictates board space constraints. Verify that the 3-state outputs meet the electrical requirements of the connected bus structure.

Part Context

This part belongs to the DS3883 series of BTL data transceivers from National Semiconductor. It is functionally related to variants such as the DS3883A and DS3884 series. These components are designed for high-speed data transfer over balanced lines, offering robust signal integrity for industrial and communication applications.

Replacement Considerations

Check for direct equivalents like the DS3883A if pinout and electrical characteristics match. Verify package compatibility with the 44-QFP form factor. Ensure any substitute maintains the 9-bit inverting transceiver specification and 3-state output behavior.
