74ACT11520DW-G

Overview

The 74ACT11520DW-G is an 8-bit magnitude comparator manufactured by Rochester Electronics, LLC. It features active low outputs indicating equality (A=B) and operates within a voltage range of up to 5V. The component is housed in a 20-SOIC package with a tube packaging style. It belongs to the ACT logic series, designed for high-speed digital applications requiring precise comparison of two 8-bit binary words.

Feature Summary

• Performs 8-bit magnitude comparison between two input words
• Provides active low output signal when inputs are equal
• Operates at standard 5V logic levels

Applications

• Digital data comparison circuits
• Equality detection systems
• Address matching logic

Procurement Notes

Verify the exact suffix 'DW-G' against official Rochester Electronics documentation to confirm pinout and electrical specifications. Ensure compatibility with existing PCB footprints for the 20-SOIC package. Confirm RoHS compliance status if required by specific manufacturing standards, as distributor listings may vary.

Selection Notes

Select this component when an 8-bit equality check is required with active low signaling. Consider the 20-SOIC package size for board space constraints. Verify that the 5V operating voltage aligns with the system's power supply rails and logic levels before integration into the design.

Part Context

Rochester Electronics specializes in sourcing and distributing obsolete and hard-to-find components. This part is part of their portfolio of legacy logic devices, providing continuity for designs that cannot be easily migrated to newer technologies. The company acts as a secondary market supplier for original manufacturer parts.

Replacement Considerations

Check for direct equivalents from other manufacturers such as Texas Instruments or ON Semiconductor in the 74ACT11520 family. Ensure pin compatibility and logical function match before substitution. Verify that any alternative meets the same 5V operation and package requirements.
