DM74AS760N Equivalent & Substitute Parts

Part Overview

The DM74AS760N is a non-inverting buffer logic IC manufactured by onsemi, featuring 2 elements with 4 bits per element in a 20-DIP package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing system support and new designs requiring this functional specification.

The primary reason for identifying substitutes is the obsolete status of the original part, which limits availability for production and maintenance applications. Substitute parts must maintain electrical and mechanical compatibility within the defined parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DM74AS760N is determined by the following critical parameters:

• Logic Type: Buffer, Non-Inverting (functional requirement)
• Number of Elements: 2 (circuit architecture requirement)
• Number of Bits per Element: 4 (data width requirement)
• Voltage - Supply: 4.5V ~ 5.5V (power supply compatibility)
• Package / Case: 20-DIP (0.300", 7.62mm) (physical and electrical interface)
• Mounting Type: Through Hole (assembly compatibility)
• Series: 74AS (logic family compatibility)

The SN74AS760N from Texas Instruments meets all these criteria and qualifies as a direct substitute. Both parts share identical functional specifications, package geometry, and electrical operating parameters within the defined supply voltage range.

Parameter Comparison

Engineering Selection Recommendations

The SN74AS760N is the qualified substitute for the DM74AS760N based on the following factors:

Functional Compatibility: Both parts implement identical logic architecture with 2 non-inverting buffer elements, 4 bits per element, and operate within the same 4.5V to 5.5V supply voltage range.

Package Compatibility: Both components use the 20-DIP (0.300", 7.62mm) package with through-hole mounting, ensuring direct physical and electrical interchangeability on existing PCBs.

Product Status: The SN74AS760N maintains active product status with established supply chains, whereas the DM74AS760N is obsolete. Selection of the Texas Instruments part ensures long-term availability and production continuity.

Compliance Status: The SN74AS760N is ROHS3 compliant, meeting modern regulatory requirements. The original DM74AS760N is RoHS non-compliant. For new designs or systems requiring regulatory compliance, the SN74AS760N is the appropriate choice.

Frequently Asked Questions (FAQ)

Q: Can the SN74AS760N directly replace the DM74AS760N in existing designs?

A: Yes. Both parts share identical logic specifications, pin configurations, and package dimensions. No circuit modifications are required for substitution.

Q: What is the difference between the output specifications listed for these parts?

A: The SN74AS760N specifies Open Collector output type with 64mA output low current. The DM74AS760N does not provide detailed output specifications. Both parts maintain compatibility within the 74AS logic family specifications.

Q: Are there any temperature operating range differences?

A: The SN74AS760N specifies 0°C to 70°C operating temperature. The DM74AS760N does not provide this specification. For applications requiring extended temperature ranges, verify the SN74AS760N operating range meets system requirements.

Q: Why is RoHS compliance status different between these parts?

A: The DM74AS760N predates RoHS3 requirements and is non-compliant. The SN74AS760N is manufactured to current ROHS3 standards. For new production or systems requiring regulatory compliance, the SN74AS760N is required.

Q: Are both parts available in the same packaging options?

A: Both parts are available in 20-DIP through-hole packages. The SN74AS760N is supplied in tube packaging. Verify packaging requirements for your assembly process.
