DM74AS10MX NAND Gate IC Equivalent & Substitute Parts

Part Overview

The DM74AS10MX is a 3-channel, 3-input NAND gate logic IC manufactured by onsemi in 14-SOIC surface mount packaging. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The DM74AS10MX operates within the 74AS logic family standard, providing TTL-compatible switching functionality for digital logic applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DM74AS10MX is determined by strict alignment with the following electrical and mechanical parameters:

• Logic type and circuit configuration (3-channel, 3-input NAND gate)
• Voltage supply range (4.5V ~ 5.5V)
• Output current specifications (2mA high, 20mA low)
• Input logic thresholds (0.8V low, 2V high)
• Propagation delay performance (4.5ns @ 5V, 50pF)
• Operating temperature range (0°C ~ 70°C)
• Surface mount technology and 14-SOIC package compatibility

All identified substitutes meet these electrical parameters identically. Package variations (14-SOIC vs. 14-SO) and packaging formats (tube, tape & reel) represent mechanical differences that do not affect electrical interchangeability.

Engineering Selection Recommendations

For applications currently using the DM74AS10MX, the following substitution path is recommended based on product status and compliance:

Primary Selection: SN74AS10DR (Texas Instruments) — Active product status with RoHS3 compliance and REACH unaffected designation. This part provides identical electrical performance in 14-SOIC packaging with tape & reel availability.

Secondary Selection: SN74AS10NSR (Texas Instruments) — Active product status with RoHS3 compliance. Electrical parameters are identical; however, the 14-SO package (5.30mm width) differs mechanically from the 14-SOIC (3.90mm width). Board layout and footprint compatibility must be verified before selection.

Tertiary Selection: SN74AS10D (Texas Instruments) — Last Time Buy status with RoHS3 compliance. Electrical and package specifications match the primary selection but procurement should account for limited availability.

All substitutes carry identical REACH and ECCN classifications (REACH Unaffected, EAR99) and moisture sensitivity level (MSL 1, Unlimited).

Frequently Asked Questions (FAQ)

Q: Can SN74AS10NSR replace DM74AS10MX directly on the PCB?

A: Electrical substitution is valid. However, SN74AS10NSR uses 14-SO packaging (5.30mm width) versus DM74AS10MX 14-SOIC (3.90mm width). Footprint compatibility must be confirmed with your PCB design. Pin count and function are identical.

Q: What is the difference between SN74AS10D and SN74AS10DR?

A: Both parts are electrically identical with matching 14-SOIC packages. The primary difference is packaging format: SN74AS10D is supplied in tube format, while SN74AS10DR is supplied in tape & reel format. SN74AS10DR has active product status; SN74AS10D is Last Time Buy.

Q: Are all substitutes RoHS compliant?

A: Yes. SN74AS10D, SN74AS10DR, and SN74AS10NSR all carry RoHS3 compliance status. The original DM74AS10MX does not specify RoHS status.

Q: Do substitutes maintain the same propagation delay performance?

A: Yes. All substitutes specify 4.5ns maximum propagation delay at 5V with 50pF load, matching the DM74AS10MX electrical performance.

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

A: SN74AS10DR and SN74AS10NSR both carry active product status, indicating ongoing manufacturing and availability. SN74AS10D is Last Time Buy, indicating limited future availability.
