DM74AS30M NAND Gate IC Equivalent & Substitute Parts

Part Overview

The DM74AS30M is a NAND Gate IC with 1 channel and 8 inputs, manufactured by onsemi in a 14-SOIC surface mount package. This component is classified as obsolete, making substitute parts necessary for new designs and ongoing production requirements. The 74AS logic family provides standard TTL-compatible switching functionality with specified propagation delay and output drive characteristics suitable for digital logic applications.

Substitute Part Grouping Explanation

Substitution for the DM74AS30M is determined by strict equivalence across the following parameters:

• Logic Type: NAND Gate
• Number of Circuits: 1
• Number of Inputs: 8
• Voltage - Supply: 4.5V ~ 5.5V
• Current - Output High, Low: 2mA, 20mA
• Input Logic Level - Low: 0.8V
• Input Logic Level - High: 2V
• Max Propagation Delay @ V, Max CL: 5ns @ 5V, 50pF
• Operating Temperature: 0°C ~ 70°C
• Package / Case: 14-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

All identified substitute parts maintain identical electrical and mechanical specifications within these parameters. Substitutes are grouped by manufacturer and product status to facilitate component selection based on availability and compliance requirements.

Parameter Comparison

Engineering Selection Recommendations

The DM74AS30M is obsolete and no longer in active production. Both SN74AS30DR and SN74AS30D from Texas Instruments are active product alternatives with identical electrical and mechanical specifications.

SN74AS30DR is supplied in Tape & Reel (TR) packaging and carries ROHS3 compliance certification, making it suitable for high-volume production environments and applications with RoHS requirements.

SN74AS30D is supplied in standard packaging and also carries ROHS3 compliance certification, suitable for applications where tape and reel packaging is not required.

Both Texas Instruments substitutes maintain full parametric equivalence with the original DM74AS30M across all specified electrical characteristics, operating conditions, and package dimensions.

Frequently Asked Questions (FAQ)

Q: Can SN74AS30DR and SN74AS30D be used interchangeably with DM74AS30M?

A: Yes. Both parts are parametrically equivalent across all specified electrical and mechanical parameters, including logic type, input/output characteristics, propagation delay, operating temperature range, and 14-SOIC package dimensions.

Q: What is the difference between SN74AS30DR and SN74AS30D?

A: The primary difference is packaging format. SN74AS30DR is supplied in Tape & Reel (TR) format for automated assembly, while SN74AS30D is supplied in standard packaging. Electrical specifications and performance are identical.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both SN74AS30DR and SN74AS30D carry ROHS3 compliance certification. The original DM74AS30M does not specify RoHS status.

Q: Will the substitutes work in existing designs using DM74AS30M?

A: Yes. The substitutes maintain identical electrical characteristics, input/output logic levels, propagation delay, supply voltage range, and operating temperature specifications. Pin configuration and package footprint are identical.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: All three parts, including the original DM74AS30M and both substitutes, have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage and handling.
