DM74AS1004AMX Equivalent & Substitute Parts

Part Overview

The DM74AS1004AMX is a 6-channel inverter logic IC manufactured by onsemi in a 14-SOIC surface mount package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The 74AS series inverter provides standard TTL-compatible logic inversion with consistent electrical characteristics across qualified manufacturer variants.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DM74AS1004AMX is determined by matching the following critical parameters:

• Logic type and circuit configuration (6-channel inverter, 1 input per channel)
• Electrical specifications (supply voltage 4.5V ~ 5.5V, output current 48mA, propagation delay 4ns @ 5V, 50pF)
• Input logic levels (low 0.8V, high 2V)
• Operating temperature range (0°C ~ 70°C)
• Package compatibility (14-SOIC surface mount)

Three substitute parts meet these criteria with variations in packaging format and product status. All substitutes maintain identical electrical performance and functional equivalence to the main part.

Engineering Selection Recommendations

For designs currently using the DM74AS1004AMX, the following selection criteria apply:

SN74AS1004ADR (Texas Instruments) is the primary substitute. This part maintains identical electrical specifications and package dimensions (14-SOIC, 0.154" width) with active product status and ROHS3 compliance. Tape & Reel packaging supports high-volume production requirements.

SN74AS1004ANSR (Texas Instruments) provides an alternative with active product status and ROHS3 compliance. The package width differs (0.209" versus 0.154"), which may affect PCB layout compatibility. Tape & Reel packaging is suitable for automated assembly.

SN74AS1004AD (Texas Instruments) is available with Last Time Buy status and ROHS3 compliance. Tube packaging is appropriate for lower-volume applications. This part shares identical package dimensions with the main part.

All three substitutes are electrically equivalent and functionally interchangeable within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can SN74AS1004ANSR be used as a direct replacement for DM74AS1004AMX?

A: SN74AS1004ANSR is electrically equivalent and functionally interchangeable. However, the package width differs (0.209" versus 0.154"), which may require PCB layout verification to confirm footprint compatibility.

Q: What is the difference between the three Texas Instruments substitutes?

A: All three parts are electrically identical. The differences are packaging format (Tube versus Tape & Reel) and product status. SN74AS1004ADR and SN74AS1004ANSR have active status; SN74AS1004AD has Last Time Buy status. Package dimensions vary between SN74AS1004ANSR and the other two parts.

Q: Are all substitutes RoHS compliant?

A: Yes. SN74AS1004AD, SN74AS1004ANSR, and SN74AS1004ADR are all ROHS3 compliant. The original DM74AS1004AMX RoHS status is not specified.

Q: Which substitute should be selected for new designs?

A: SN74AS1004ADR is recommended for new designs due to active product status, ROHS3 compliance, identical package dimensions, and Tape & Reel availability for production volumes.

Q: Are there any temperature or voltage operating differences between the main part and substitutes?

A: No. All parts operate identically across the 0°C ~ 70°C temperature range and 4.5V ~ 5.5V supply voltage range with matching propagation delay and output current specifications.
