SN74ALS679N

Comparators Overview

The SN74ALS679N is a 12-bit address comparator from the Texas Instruments ALS series, housed in a 20-pin PDIP package. It operates on a single 5V supply (4.5V to 5.5V) with a typical supply current of 17mA. The device features inverted outputs and is designed for high-speed digital logic applications requiring magnitude comparison of 12-bit binary words.

Comparators Feature Summary

• Performs 12-bit magnitude comparison between two binary inputs
• Provides active-high output signals indicating comparison results
• Utilizes Advanced Low-power Schottky (ALS) technology for speed and efficiency

Comparators Applications

• Memory address decoding systems
• Digital control logic circuits
• Computer peripheral interface design

Comparators Procurement Notes

Verify the specific manufacturer source and authenticity before purchase. Confirm that the PDIP-20 package matches your PCB footprint requirements. Ensure the operating voltage range aligns with your system's power supply specifications. Check for any RoHS compliance documentation if required by your manufacturing standards.

Comparators Selection Notes

Select this component when a 12-bit comparator with inverted outputs is required within the ALS logic family. Consider the PDIP-20 package constraints for through-hole assembly. Evaluate the 17mA supply current against your system's power budget. Compare performance metrics with other ALS comparators if pin compatibility or specific output configurations differ.

Comparators Part Context

This part belongs to the SN74ALS679 series of 12-bit address comparators manufactured by Texas Instruments. It is part of the broader SN74xx logic family, specifically utilizing Advanced Low-power Schottky technology. The 'N' suffix denotes the plastic dual-in-line package variant.

Comparators Replacement Considerations

Check for direct equivalents such as the SN74ALS679 without the 'N' suffix for different packaging. Verify compatibility with other 12-bit ALS comparators from Texas Instruments or third-party manufacturers offering pin-compatible alternatives.
