DM74AS576N Equivalent & Substitute Parts

Part Overview

The DM74AS576N is a Flip Flop Element Bit logic integrated circuit manufactured by onsemi, housed in a 20-DIP (0.300", 7.62mm) package. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and component procurement.

The 74AS series represents a standard logic family for digital applications requiring flip-flop functionality. Due to the obsolete status of the DM74AS576N, sourcing equivalent parts from active manufacturers ensures long-term availability and supply chain continuity.

Substitute Part Grouping Explanation

Substitution of the DM74AS576N is determined by strict alignment of the following parameters:

• Series Compatibility: Both parts must belong to the 74AS logic family
• Package Equivalence: Identical 20-DIP (0.300", 7.62mm) through-hole package
• Functional Classification: Flip-flop D-type logic element
• Pin Configuration: Same supplier device package (20-PDIP)

The SN74AS576N from Texas Instruments satisfies all substitution criteria. It maintains the same 74AS series designation, identical physical package, and equivalent functional classification as a D-type flip-flop element. Both parts share the same base product number (74AS576) and are housed in the 20-PDIP package format.

Engineering Selection Recommendations

The SN74AS576N is the direct equivalent for DM74AS576N replacement applications. Selection is justified by:

• Product Status Alignment: The SN74AS576N maintains active production status, ensuring reliable procurement against the obsolete DM74AS576N
• Regulatory Compliance: The SN74AS576N achieves ROHS3 compliance, providing enhanced environmental and regulatory positioning compared to the non-compliant DM74AS576N
• Certification Equivalence: Both parts share identical REACH and ECCN classifications, confirming regulatory interchangeability
• Physical and Functional Compatibility: Identical package format, pin configuration, and series designation guarantee direct substitution without circuit redesign

Frequently Asked Questions (FAQ)

Q: Can the SN74AS576N directly replace the DM74AS576N without circuit modification?

A: Yes. Both parts share identical package specifications (20-DIP, 0.300" spacing), supplier device package designation (20-PDIP), and 74AS series classification. Direct pin-for-pin substitution is supported.

Q: What is the significance of the product status difference?

A: The DM74AS576N is classified as obsolete, indicating discontinued manufacturing and limited availability. The SN74AS576N is in active production, ensuring consistent supply and long-term component availability for new procurement and system maintenance.

Q: Does the RoHS compliance difference affect substitution?

A: The SN74AS576N achieves ROHS3 compliance while the DM74AS576N is non-compliant. For applications subject to RoHS regulations or environmental standards, the SN74AS576N provides superior compliance positioning. Both parts remain functionally equivalent for legacy system support.

Q: Are there any package or mounting considerations?

A: Both parts utilize identical through-hole mounting in 20-DIP packages with 0.300" (7.62mm) spacing. No PCB layout or assembly process modifications are required for substitution.

Q: What regulatory certifications apply to both parts?

A: Both the DM74AS576N and SN74AS576N are classified under ECCN EAR99 and HTSUS 8542.39.0001. Both maintain REACH Unaffected status, confirming regulatory equivalence for international applications.
