DM74ALS30AMX NAND Gate IC Equivalent & Substitute Parts

Part Overview

The DM74ALS30AMX is a NAND Gate IC featuring 1 channel with 8 inputs in a 14-SOIC surface mount package, manufactured by onsemi. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement continuity. The 74ALS logic family provides standard TTL-compatible switching functionality with specified electrical performance across industrial temperature ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DM74ALS30AMX is determined by strict equivalence across the following critical parameters:

• Logic Type: NAND Gate configuration
• Number of Circuits: 1 channel
• Number of Inputs: 8 inputs per gate
• Voltage Supply Range: 4.5V ~ 5.5V
• Output Current Specifications: 400µA (high), 8mA (low)
• Input Logic Thresholds: 0.8V (low), 2V (high)
• Propagation Delay: 12ns @ 5V, 50pF load
• Operating Temperature Range: 0°C ~ 70°C
• Package Type: 14-SOIC surface mount
• Base Series: 74ALS

The identified substitute parts maintain identical electrical and mechanical specifications, differing only in manufacturer, product status, and packaging format (tube or tape & reel).

Parameter Comparison

Engineering Selection Recommendations

SN74ALS30ADR (Texas Instruments, Tape & Reel) is the primary substitute for new designs and procurement. This part carries Active product status, ensuring long-term availability and supply chain stability. It is ROHS3 compliant and maintains full electrical and mechanical equivalence to the DM74ALS30AMX.

SN74ALS30AD (Texas Instruments, Tube) serves as an alternative substitute with Last Time Buy status. This part is suitable for applications requiring tube packaging format and remains ROHS3 compliant with identical electrical specifications.

Both Texas Instruments substitutes provide equivalent performance within the specified 74ALS logic family parameters and are suitable for direct replacement in applications currently using the obsolete onsemi DM74ALS30AMX.

Frequently Asked Questions (FAQ)

Q: Can SN74ALS30ADR replace DM74ALS30AMX directly in existing designs?

A: Yes. The SN74ALS30ADR maintains identical electrical specifications, logic configuration, and 14-SOIC package dimensions. No circuit modifications are required for substitution.

Q: What is the difference between SN74ALS30AD and SN74ALS30ADR?

A: Both parts are electrically identical. The primary difference is packaging format: SN74ALS30AD is supplied in tube packaging, while SN74ALS30ADR is supplied in tape & reel format. Selection depends on assembly process requirements and procurement volume.

Q: Why is the DM74ALS30AMX listed as obsolete?

A: Obsolete status indicates the manufacturer (onsemi) has discontinued production. Texas Instruments continues to manufacture equivalent 74ALS30 variants, ensuring design continuity through the identified substitutes.

Q: Are there any compliance differences between the substitute parts and the original?

A: The Texas Instruments substitutes (SN74ALS30AD and SN74ALS30ADR) are ROHS3 compliant. All three parts maintain REACH Unaffected status and MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the recommended substitute for high-volume production?

A: SN74ALS30ADR is recommended for production applications due to its Active product status, tape & reel packaging format suitable for automated assembly, and assured long-term availability.
