IDT74FCT521CTPYG

Comparators Overview

The IDT74FCT521CTPYG is an 8-bit identity comparator from the Renesas 74FCT series. It features active low outputs indicating equality (A=B) between two 8-bit inputs. The device operates on a single 5V supply (4.75V to 5.25V). Key electrical parameters include a propagation delay of 6ns and 7.2ns, with a maximum quiescent current of 10µA. It is housed in a 20-SSOP package and supports surface mount installation.

Comparators Feature Summary

• Performs 8-bit magnitude comparison to determine input equality
• Provides active low output signal when inputs match
• Operates with standard 5V CMOS logic levels

Comparators Applications

• Digital data bus monitoring for parity or address matching
• System configuration verification circuits
• Memory address decoding validation

Comparators Procurement Notes

Verify the specific suffix 'PYG' corresponds to the 20-SSOP package and tube packaging format. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure the operating temperature range meets your environmental requirements before finalizing procurement orders.

Comparators Selection Notes

Select this component when an 8-bit equality check is required within a 5V logic system. The 74FCT series offers faster switching speeds compared to standard 74HC devices. Consider the 20-SSOP footprint constraints during PCB layout design to ensure adequate spacing for the package dimensions.

Comparators Part Context

This part belongs to the IDT 74FCT logic family, designed for high-speed digital applications. It serves as a specialized comparator within the broader portfolio of logic integrated circuits provided by Renesas Electronics Corporation, targeting systems requiring precise digital value matching.

Comparators Replacement Considerations

The IDT74FCT521ATQG is a verified substitute offering identical logical functionality. Both parts share the same 8-bit identity comparison capability and compatible pinout configurations for direct replacement in existing designs.
