SN74AS850AFN

Overview

The SN74AS850AFN is a high-speed AS-series 16-line input multiplexer manufactured by Texas Instruments. It features tri-state outputs and is housed in a 28-pin PLCC package. The device operates within a temperature range of 0 to 70 degrees Celsius, supporting standard commercial applications.

Feature Summary

• Provides 16-to-1 data selection capability
• Features tri-state output control for bus driving
• Utilizes AS-series technology for high-speed performance

Applications

• Data routing in digital systems
• Signal switching applications
• Multiplexing in communication interfaces

Procurement Notes

Verify the specific suffix 'FN' against official Texas Instruments documentation to confirm pinout and electrical characteristics match your design requirements. Ensure the PLCC package type is compatible with your PCB footprint and assembly process before finalizing procurement.

Selection Notes

Select this component when a 16-channel multiplexer with tri-state outputs is required. The AS series offers faster propagation delays compared to standard TTL or LS families. Confirm that the operating voltage and current drive capabilities meet the load requirements of the destination circuitry.

Part Context

This part belongs to the Texas Instruments SN74AS logic family, known for advanced Schottky technology. It serves as a signal switch or multiplexer, distinct from standard logic gates. The device integrates multiple input channels into a single selectable output path.

Replacement Considerations

Check for SN74AS850 variants with different suffixes (e.g., DW) if package changes are acceptable. Verify functional equivalence with other 16:1 muxes from the same manufacturer, ensuring pin compatibility and electrical specs align.
