DM74ALS151MX

Overview

The DM74ALS151MX is an octal digital multiplexer manufactured by Fairchild Semiconductor. It selects one of eight data inputs based on three address lines and provides both true and complement outputs. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports surface-mount installation in a 16-lead SOIC package. It features advanced low power Schottky technology, ensuring switching specifications are guaranteed over the full temperature and voltage range.

Feature Summary

• Provides selection of one of eight data sources using three address inputs
• Features both true and complement output configurations
• Includes a strobe input for enabling or disabling the multiplexer function

Applications

• Data routing in microprocessor systems
• Asynchronous bidirectional data buses
• Memory addressing applications

Procurement Notes

Verify the specific manufacturer marking and date code against official Fairchild Semiconductor documentation to confirm authenticity. Ensure the component matches the 16-lead SOIC physical dimensions and pinout configuration. Check for any obsolescence notices or lifecycle status updates from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when an octal multiplexer with Schottky speed and low power consumption is required. It is suitable for designs needing simultaneous true and complement outputs. Verify that the system logic levels align with the ALS family specifications and that the operating temperature range meets the application requirements.

Part Context

This part belongs to the DM74ALS series of advanced low power Schottky logic devices. It serves as a functional equivalent to standard TTL multiplexers but offers improved performance characteristics. The device is designed for use in high-speed digital circuits requiring reliable data selection capabilities.

Replacement Considerations

Check for direct cross-references such as the DM74ALS151N or other variants within the same ALS family. Ensure any substitute maintains the 16-lead SOIC package and identical pinout compatibility.
