Key Parameters

Substitute Part Grouping Explanation

Substitution for the DM74AS1034AM is determined by strict equivalence across the following critical parameters: logic type (non-inverting buffer), element count (6), bits per element (1), output current specifications (48mA high and low), supply voltage range (4.5V ~ 5.5V), operating temperature range (0°C ~ 70°C), package type (14-SOIC), and mounting method (surface mount). All substitute parts listed maintain identical electrical and mechanical specifications, ensuring direct functional replacement within the 74AS logic series.

Engineering Selection Recommendations

For new designs and procurement, SN74AS1034ADR from Texas Instruments is the preferred substitute. This part maintains active product status, ensuring long-term availability and supply chain stability. The SN74AS1034ADR is supplied in Tape & Reel (TR) packaging, which is standard for automated assembly operations.

SN74AS1034AD from Texas Instruments is an alternative substitute available in Tube packaging. This part carries Last Time Buy status, indicating limited future availability. Both Texas Instruments substitutes are ROHS3 compliant, meeting current environmental and regulatory requirements.

The DM74AS1034AM, being obsolete, should be replaced in active designs. All three parts share identical electrical specifications and 14-SOIC package geometry, enabling direct pin-for-pin substitution without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can SN74AS1034AD and SN74AS1034ADR be used interchangeably with DM74AS1034AM?

A: Yes. Both Texas Instruments parts are direct functional equivalents. The difference between them is packaging format: SN74AS1034AD uses Tube packaging, while SN74AS1034ADR uses Tape & Reel packaging. Electrical performance and pin configuration are identical.

Q: What is the difference between Tube and Tape & Reel packaging?

A: Tube packaging is suitable for manual handling and small-quantity applications. Tape & Reel packaging is designed for automated pick-and-place assembly equipment. Both contain the same component with identical specifications.

Q: Why is the DM74AS1034AM listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. Substitute parts from active manufacturers ensure continued availability for replacement and new applications.

Q: Are there any electrical differences between the onsemi and Texas Instruments versions?

A: No. All three parts meet identical electrical specifications: 6-element non-inverting buffer, 48mA output current, 4.5V to 5.5V supply voltage, and 0°C to 70°C operating temperature range.

Q: Does the 14-SOIC package remain the same across all three parts?

A: Yes. All parts use the 14-SOIC (0.154", 3.90mm Width) surface mount package, ensuring mechanical and electrical compatibility on the same PCB layout.

Q: What does ROHS3 compliance mean?

A: ROHS3 compliance indicates the part meets the Restriction of Hazardous Substances Directive, restricting specific hazardous materials in electrical and electronic equipment. The Texas Instruments substitutes are ROHS3 compliant; the onsemi part does not specify this status.
