AM25LS2521PC

Comparators Overview

The AM25LS2521PC is an eight-bit equal-to comparator integrated circuit manufactured by Advanced Micro Devices. It utilizes TTL technology and operates on a nominal 5 V supply voltage. The device is housed in a 20-pin dual in-line package (PDIP) designed for through-hole mounting. It supports a commercial operating temperature range of 0°C to 70°C. The component functions as a magnitude comparator, specifically evaluating two 4-bit words to determine equality.

Comparators Feature Summary

• Performs eight-bit magnitude comparison operations
• Outputs results indicating equality between input words
• Compatible with standard TTL logic families

Comparators Applications

• Microprocessor enable control circuits
• Optional address decoding systems
• Digital control systems requiring word equality verification

Comparators Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm pinout compatibility and electrical specifications. Ensure the procurement source provides valid traceability for the component's manufacturing origin. Confirm that the package type matches the required PCB footprint and mounting style for the intended assembly process.

Comparators Selection Notes

Select this component when an eight-bit equality check is required within a TTL-based digital design. Consider the DIP-20 package constraints regarding board space and thermal dissipation. Evaluate the 5 V supply requirement against existing system power rails. Verify that the commercial temperature range meets the environmental conditions of the final application.
