74AS850AN

Overview

The 74AS850AN is a high-speed, TTL-compatible 1-of-16 data selector and multiplexer manufactured by Rochester Electronics. This integrated circuit selects one of sixteen available data inputs and routes the chosen signal to a single output line. The device features three-state outputs, allowing for direct bus-oriented connections without additional interface hardware. It is designed for applications requiring fast data routing and selection within digital logic systems.

Feature Summary

• High-speed operation with TTL compatibility
• Selects one of sixteen data inputs
• Features three-state outputs for bus-oriented connections

Applications

• Data routing in digital communication systems
• Bus-oriented switching applications
• Signal selection in computer architecture

Procurement Notes

Verify the manufacturer marking matches Rochester Electronics, LLC. Confirm the package type is DIP-24. Check for date codes to ensure component freshness. Request original packaging documentation if required for quality assurance. Validate part number authenticity through authorized channels.

Selection Notes

Choose this component when a high-speed 16-channel multiplexer with three-state outputs is required. Ensure system voltage levels match TTL standards. Consider pin compatibility if replacing legacy designs. Verify propagation delay requirements against application timing constraints.

Part Context

Rochester Electronics specializes in continuing source solutions for obsolete and end-of-life semiconductors. The 74AS850AN belongs to the 74AS series, known for advanced Schottky technology. This product supports lifecycle management for industrial and commercial electronics no longer produced by original manufacturers.

Replacement Considerations

Direct substitutes include other 74AS850 variants from different manufacturers. Verify pinout compatibility before substitution. Ensure electrical characteristics meet original design specifications.
