SN74LS686NT

Comparators Overview

The SN74LS686NT is an 8-bit magnitude and identity comparator manufactured by Texas Instruments. It belongs to the LS-TTL logic family and is housed in a 24-pin plastic Dual In-line Package (DIP). The device features inverted outputs for its comparison functions. It operates within a commercial temperature range, with a maximum operating temperature of 70 °C and a minimum of 0 °C. The component utilizes through-hole terminals with a dual pin configuration and a standard pitch of 2.54 mm.

Comparators Feature Summary

• Performs 8-bit magnitude and identity comparisons using TTL technology
• Provides inverted output signals for comparison results
• Designed for commercial temperature operation environments

Comparators Applications

• Digital data comparison circuits
• Address decoding systems
• Logic control applications requiring magnitude evaluation

Comparators Procurement Notes

Verify that the specific part number matches the required LS-TTL series specifications. Confirm the DIP-24 package type aligns with board layout constraints. Ensure the commercial temperature rating meets operational requirements. Check RoHS compliance status as indicated in official documentation, noting potential non-compliance markers in some records. Validate manufacturer origin from Texas Instruments or authorized distributors.

Comparators Selection Notes

Select this component when an 8-bit magnitude comparator with inverted outputs is required within the LS-TTL family. Consider the DIP-24 package for through-hole assembly processes. Evaluate the commercial temperature range suitability for the intended environment. Compare against other 8-bit comparators if different output polarities or logic families are preferred.

Comparators Part Context

This component is part of the SN74LS686 series of 8-bit magnitude/identity comparators. It shares functional characteristics with other devices in the LS-TTL logic family, offering standardized digital comparison capabilities. The PDIP24 package is common for this class of integrated circuits, facilitating easy integration into legacy and modern through-hole designs.

Comparators Replacement Considerations

Compatible substitutes include other SN74LS686 variants such as SN74LS686N or SN74LS686NS, provided they match the PDIP24 package and LS-TTL electrical characteristics. Verify pinout compatibility before substitution.
