DM74ALS00AMX Equivalent & Substitute Parts

Part Overview

The DM74ALS00AMX is a NAND Gate IC with 4 channels and 2 inputs per channel, 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 production continuity. The part operates within the 4.5V to 5.5V supply voltage range and is suitable for standard logic applications requiring NAND gate functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the DM74ALS00AMX is determined by strict equivalence across the following parameters: logic type (NAND Gate), circuit count (4 channels), input count (2 inputs per channel), supply voltage range (4.5V ~ 5.5V), output current specifications (400µA high, 8mA low), input logic levels (0.8V low, 2V high), propagation delay (11ns @ 5V, 50pF), operating temperature range (0°C ~ 70°C), and surface mount configuration.

The substitute parts are grouped into two categories:

Direct Substitutes: Parts with identical electrical specifications and the same 14-SOIC package footprint (0.154", 3.90mm width). These provide pin-for-pin compatibility without PCB layout modifications.

Similar Substitutes: Parts with identical electrical specifications but different package dimensions within the 14-SO family (0.209", 5.30mm width). These require PCB footprint adjustment but maintain full functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

For applications currently using the DM74ALS00AMX, the SN74ALS00ADR from Texas Instruments is the primary substitute. This part maintains active product status, ensuring long-term availability and supply chain stability. It is ROHS3 compliant and available in Tape & Reel packaging, which is standard for production environments.

The SN74ALS00AD is suitable as a secondary option where tube packaging is acceptable. This part carries Last Time Buy status, indicating limited future availability.

The SN74ALS00ANSR provides functional equivalence with identical electrical specifications but requires PCB footprint modification due to its 14-SO package with 5.30mm width versus the standard 3.90mm width. This substitution is appropriate only when PCB layout changes are feasible.

Frequently Asked Questions (FAQ)

Q: Can SN74ALS00ADR be used as a direct replacement for DM74ALS00AMX without PCB modifications?

A: Yes. The SN74ALS00ADR shares identical electrical specifications and the same 14-SOIC package footprint (0.154", 3.90mm width), enabling direct pin-for-pin substitution without PCB layout changes.

Q: What is the difference between SN74ALS00AD and SN74ALS00ADR?

A: Both parts are electrically identical and use the same 14-SOIC package. The primary difference is packaging format: SN74ALS00AD is supplied in Tube packaging, while SN74ALS00ADR is supplied in Tape & Reel format. Tape & Reel is standard for automated assembly processes.

Q: Why does SN74ALS00ANSR have a different package width?

A: The SN74ALS00ANSR uses a 14-SO package with 5.30mm width compared to the standard 3.90mm width of the 14-SOIC package. While electrically equivalent, this dimensional difference requires PCB footprint adjustment before implementation.

Q: Is the DM74ALS00AMX still available for purchase?

A: The DM74ALS00AMX is classified as obsolete. Substitute parts from Texas Instruments, particularly the SN74ALS00ADR with active product status, are recommended for new designs and ongoing production.

Q: Are all substitute parts RoHS compliant?

A: Yes. All Texas Instruments substitute parts (SN74ALS00AD, SN74ALS00ADR, and SN74ALS00ANSR) are ROHS3 compliant, meeting environmental and regulatory requirements for modern manufacturing.
