DM74ALS1005MX Equivalent & Substitute Parts

Part Overview

The DM74ALS1005MX is a 6-channel inverter logic IC manufactured by onsemi in 14-SOIC surface mount packaging. This part features open collector outputs and operates within the 4.5V to 5.5V supply voltage range. The DM74ALS1005MX is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the DM74ALS1005MX is determined by the following critical parameters:

• Logic type (Inverter) and circuit configuration (6 channels, 1 input per channel)
• Open collector output feature
• Supply voltage range (4.5V ~ 5.5V)
• Input logic levels (Low: 0.8V, High: 2V)
• Operating temperature range (0°C ~ 70°C)
• Surface mount packaging in 14-pin configuration

Substitute parts are grouped into two categories:

Direct Equivalents maintain identical electrical performance specifications including output current (24mA) and propagation delay (30ns @ 5V, 50pF). These parts use the base number 74ALS1005.

Similar Equivalents share the same logic function and core parameters but differ in output current (8mA) and propagation delay (54ns @ 5V, 50pF). These parts use the base number 74ALS05. While functionally compatible, they exhibit reduced output drive capability and increased propagation delay.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: SN74ALS1005DR

The SN74ALS1005DR from Texas Instruments is the preferred direct equivalent. It maintains identical electrical specifications (24mA output current, 30ns propagation delay) and is currently in active production status. The part is ROHS3 compliant and available in the standard 14-SOIC (0.154", 3.90mm) package. This selection ensures drop-in compatibility with the original DM74ALS1005MX design.

Secondary Recommendation: SN74ALS1005NSR

The SN74ALS1005NSR provides identical electrical performance to the DM74ALS1005MX with active product status and ROHS3 compliance. The primary difference is the wider 14-SOIC package (0.209", 5.30mm). This part is suitable when PCB layout accommodates the larger package footprint.

Alternative Selection: SN74ALS05ADR

The SN74ALS05ADR is an active, ROHS3-compliant alternative when reduced output current (8mA) and increased propagation delay (54ns) are acceptable within system requirements. This part offers the advantage of active production status and is available in the standard 14-SOIC (0.154", 3.90mm) package.

Avoid: SN74ALS1005D and SN74ALS05AD

Both parts carry Last Time Buy status, indicating limited future availability. These should be selected only when primary and secondary recommendations are unavailable.

Frequently Asked Questions (FAQ)

Q: Can SN74ALS05ADR replace DM74ALS1005MX directly?

A: SN74ALS05ADR is functionally compatible but with performance differences. Output current is reduced from 24mA to 8mA, and propagation delay increases from 30ns to 54ns. Substitution is valid only if the application circuit tolerates these reduced specifications.

Q: What is the difference between 14-SOIC (0.154", 3.90mm) and 14-SOIC (0.209", 5.30mm)?

A: Both are 14-pin SOIC packages with different body widths. The 0.154" width is the standard narrow SOIC; the 0.209" width is the wider variant. PCB footprints differ and must be verified before substitution. Parts with different widths are not interchangeable on the same PCB layout.

Q: Why is DM74ALS1005MX obsolete?

A: The part is no longer manufactured by onsemi. Texas Instruments continues production of equivalent 74ALS1005 variants, making cross-manufacturer substitution necessary for ongoing supply.

Q: Are all substitute parts ROHS3 compliant?

A: All Texas Instruments substitute parts listed are ROHS3 compliant. The original DM74ALS1005MX is REACH unaffected but does not carry explicit ROHS certification.

Q: What is the difference between packaging designations D, DR, and NSR?

A: D indicates standard packaging; DR indicates Cut Tape and Digi-Reel packaging; NSR indicates Tape & Reel packaging. These designations reflect distribution format and do not affect electrical performance or physical package dimensions.

Q: Can I use SN74ALS05ANSR as a substitute?

A: SN74ALS05ANSR is functionally compatible with reduced output current (8mA) and increased propagation delay (54ns). The wider 14-SOIC package (0.209", 5.30mm) requires PCB layout verification before substitution.
