Key Parameters

Substitute Part Grouping Explanation

Substitution of the DM74AS1034AN is determined by strict equivalence across the following critical parameters:

• Logic Type: Buffer, Non-Inverting (6 elements, 1 bit per element)
• Output Current Capability: 48mA high and low
• Supply Voltage Range: 4.5V ~ 5.5V
• Operating Temperature Range: 0°C ~ 70°C
• Package Type: 14-DIP through-hole configuration
• Base Product Number: 74AS1034

The SN74AS1034AN from Texas Instruments meets all these criteria and qualifies as a parametric equivalent. Both devices share identical functional specifications, electrical characteristics, and physical packaging, enabling direct substitution in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

The SN74AS1034AN from Texas Instruments is the direct substitute for the obsolete DM74AS1034AN. Both devices are classified as REACH Unaffected and carry identical export control classifications (EAR99), ensuring regulatory compliance across both sourcing and application contexts.

The SN74AS1034AN maintains active product status with established supply availability (3368 pcs in stock), whereas the DM74AS1034AN is obsolete. For new designs or system maintenance requiring continued operation, the SN74AS1034AN provides electrical and mechanical compatibility without circuit modification.

The Texas Instruments device carries RoHS3 compliance certification, providing additional environmental compliance assurance for applications subject to hazardous substance restrictions.

Frequently Asked Questions (FAQ)

Q: Can the SN74AS1034AN replace the DM74AS1034AN in existing circuits?

A: Yes. Both devices share identical logic type, element count, output current ratings, supply voltage range, operating temperature specifications, and 14-DIP package configuration. Direct substitution is supported without circuit redesign.

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

A: The DM74AS1034AN is obsolete, indicating onsemi has discontinued production and support. The SN74AS1034AN is active, meaning Texas Instruments continues manufacturing and providing technical support. For ongoing supply chain requirements, the active part is the appropriate selection.

Q: Are there packaging differences between these parts?

A: Both devices use 14-DIP through-hole packages with identical 0.300" (7.62mm) pitch. The DM74AS1034AN is supplied in standard packaging, while the SN74AS1034AN is supplied in tube packaging. Both are suitable for through-hole PCB assembly without modification.

Q: Do compliance certifications differ between the two parts?

A: Both devices are REACH Unaffected and classified as EAR99 for export control purposes. The SN74AS1034AN additionally carries RoHS3 compliance certification, providing enhanced environmental compliance documentation for regulated applications.

Q: What are the key electrical parameters that define substitution eligibility?

A: Substitution is determined by matching logic type (Buffer, Non-Inverting), element configuration (6 elements, 1 bit per element), output current capability (48mA high and low), supply voltage range (4.5V ~ 5.5V), and operating temperature range (0°C ~ 70°C). All parameters are identical between the two devices.
