DM74ALS05AM Equivalent & Substitute Parts

Part Overview

The DM74ALS05AM is a 6-channel inverter IC with open collector outputs in a 14-SOIC surface mount package, manufactured by onsemi. This logic component is currently classified as obsolete, which necessitates identification of equivalent and substitute parts for ongoing design requirements and production needs. Active alternatives from Texas Instruments are available with identical or enhanced electrical characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DM74ALS05AM is determined by strict adherence to the following electrical and mechanical parameters:

Critical Parameters for Direct Substitution:

• Logic Type: Inverter
• Number of Circuits: 6
• Number of Inputs: 1
• Features: Open Collector
• Voltage - Supply: 4.5V ~ 5.5V
• Input Logic Level - Low: 0.8V
• Input Logic Level - High: 2V
• Operating Temperature: 0°C ~ 70°C
• Mounting Type: Surface Mount
• Moisture Sensitivity Level: 1 (Unlimited)

Allowed Variation Parameters:

• Current - Output High, Low: 8mA or 24mA (higher current capability is acceptable)
• Max Propagation Delay: 54ns or 30ns (faster propagation is acceptable)
• Package / Case: 14-SOIC (0.154", 3.90mm Width) or 14-SO (0.209", 5.30mm Width)
• Packaging Format: Cut Tape, Tape & Reel, or Tube
• Product Status: Active or Last Time Buy (preferred over Obsolete)

Substitute parts are grouped into two categories based on output current capability: standard 8mA output current parts and enhanced 24mA output current parts. Both categories maintain identical logic functionality and electrical interface specifications.

Engineering Selection Recommendations

For Direct Pin-Compatible Replacement (Identical Electrical Performance):

SN74ALS05ADR is the primary direct substitute. This part maintains identical output current (8mA) and propagation delay (54ns) specifications while offering Active product status and ROHS3 compliance. The Cut Tape & Digi-Reel packaging format provides flexibility for both prototype and production environments.

For Enhanced Performance Applications:

The SN74ALS1005 series (SN74ALS1005DR or SN74ALS1005NSR) provides improved electrical characteristics with 24mA output current capability and faster propagation delay (30ns). These parts are functionally compatible within the same logic family and supply voltage range. SN74ALS1005DR is recommended for standard 14-SOIC (0.154") package requirements with Active status availability.

For Last Time Buy Scenarios:

SN74ALS05AD and SN74ALS1005D are available in Last Time Buy status. These parts maintain full electrical compatibility but have limited future availability. Selection should account for long-term supply chain requirements.

Package Considerations:

Parts designated with NSR suffix (SN74ALS05ANSR, SN74ALS1005NSR) use the wider 14-SO package (0.209", 5.30mm Width) in Tape & Reel format. These are suitable for applications where package width variation is acceptable and tape reel packaging is preferred for automated assembly.

All recommended substitutes carry ROHS3 compliance and REACH Unaffected status, meeting modern regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can SN74ALS1005 series parts replace DM74ALS05AM directly?

A: Yes. The SN74ALS1005 series maintains identical logic functionality, pin configuration, and supply voltage specifications. The enhanced output current (24mA vs. 8mA) and faster propagation delay (30ns vs. 54ns) are improvements that do not compromise compatibility. Designs requiring the original 8mA output current specification should use SN74ALS05ADR instead.

Q: What is the difference between 14-SOIC and 14-SO packages?

A: Both are 14-pin surface mount packages with identical pin assignments. The primary difference is package width: 14-SOIC measures 0.154" (3.90mm) while 14-SO measures 0.209" (5.30mm). PCB layout and footprint compatibility must be verified before selecting parts with different package widths.

Q: Are all substitute parts RoHS compliant?

A: All Texas Instruments substitute parts listed carry ROHS3 compliance. The original onsemi DM74ALS05AM is REACH Unaffected. All parts maintain Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements.

Q: Which substitute offers the best long-term availability?

A: SN74ALS05ADR and SN74ALS1005DR both carry Active product status, indicating ongoing manufacturing and availability. Parts with Last Time Buy status (SN74ALS05AD, SN74ALS1005D) have limited future availability and should be selected only when Active alternatives are unsuitable.

Q: Can I use SN74ALS05ANSR in place of SN74ALS05ADR?

A: Both parts are electrically identical with matching output current and propagation delay. The difference is packaging format: SN74ALS05ANSR uses Tape & Reel format in the wider 14-SO package, while SN74ALS05ADR uses Cut Tape & Digi-Reel format in the standard 14-SOIC package. Selection depends on assembly equipment compatibility and PCB footprint requirements.

Q: What is the quiescent current specification for these parts?

A: The DM74ALS05AM and SN74ALS05 series do not specify maximum quiescent current in the provided data. The SN74ALS1005 series specifies 3mA maximum quiescent current, representing a measurable difference for low-power applications.
