SN74ALS518NS

Comparators Overview

The SN74ALS518NS is an 8-bit identity comparator from Texas Instruments' ALS logic series, housed in a 20-pin SOIC package. It features open-collector outputs and includes 20-kΩ pull-up resistors on the Q inputs for analog or switch data compatibility. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a commercial temperature range of 0°C to +70°C.

Comparators Feature Summary

• Provides 8-bit magnitude comparison with open-collector outputs
• Integrates 20-kΩ pull-up resistors on Q inputs for analog or switch data handling

Comparators Applications

• Digital magnitude comparison circuits
• Analog signal monitoring systems
• Switch data processing interfaces

Comparators Procurement Notes

Verify the specific suffix 'NS' corresponds to the SOIC-20 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure supply chain partners provide valid traceability records for this active component.

Comparators Selection Notes

Select this component for applications requiring precise 8-bit equality detection with open-drain output flexibility. The integrated pull-up resistors simplify interface design for mixed-signal environments. Verify that the ALS series speed and power characteristics align with system requirements compared to standard TTL alternatives.

Comparators Part Context

This part belongs to the SN74ALS518 family of 8-bit identity comparators manufactured by Texas Instruments. It is designed for high-speed digital logic applications where accurate magnitude comparison is critical. The device complements other ALS series logic components for complex digital system designs.

Comparators Replacement Considerations

Direct substitutes include SN74ALS518N (DIP package) and SN74ALS518DW (TSSOP package). Verify pinout compatibility and package dimensions before substitution. Functional equivalence exists across the SN74ALS518 series variants.
