DM74ALS00AM NAND Gate IC Equivalent & Substitute Parts

Part Overview

The DM74ALS00AM is a 4-channel 2-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 DM74ALS00AM operates within the 74ALS logic family standard, which defines compatible electrical and mechanical parameters across multiple manufacturers and packaging variants.

Substitute Part Grouping Explanation

Substitution of the DM74ALS00AM is determined by strict adherence to the 74ALS logic family standard. All substitute parts must maintain identical electrical parameters: 4.5V to 5.5V supply voltage, 400µA/8mA output current ratings, 0.8V/2V input logic thresholds, and 11ns maximum propagation delay at 5V with 50pF load. Mechanical compatibility requires surface mount technology with 14-pin SOIC packaging. Substitutes are grouped into three categories based on packaging and product status:

Direct Manufacturer Equivalent (SN74ALS00ADR): Identical electrical and mechanical specifications with active product status and tape & reel packaging.

Similar Manufacturer Part (SN74ALS00ANSR): Maintains all electrical parameters with 14-SO package variant (0.209", 5.30mm width) and active product status.

Parametric Equivalent (SN74ALS00AD): Identical electrical and mechanical specifications with last-time-buy product status and tube packaging.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: SN74ALS00ADR (Texas Instruments)

The SN74ALS00ADR is the recommended substitute for new designs and ongoing procurement. This part maintains active product status with full ROHS3 compliance and identical electrical and mechanical specifications to the DM74ALS00AM. Tape & reel packaging supports automated assembly processes. This part provides the longest product lifecycle support.

Alternative Selection: SN74ALS00AD (Texas Instruments)

The SN74ALS00AD offers identical electrical and mechanical specifications with ROHS3 compliance. Product status is last-time-buy, indicating limited future availability. Tube packaging is suitable for manual assembly or lower-volume applications. This part is appropriate for legacy system maintenance where existing inventory may be depleted.

Package Variant: SN74ALS00ANSR (Texas Instruments)

The SN74ALS00ANSR maintains all electrical parameters with active product status and ROHS3 compliance. The 14-SO package (0.209", 5.30mm width) differs mechanically from the standard 14-SOIC (0.154", 3.90mm width). This variant is suitable only when PCB layout accommodates the wider package footprint and when active product status is required.

Frequently Asked Questions (FAQ)

Q: Can SN74ALS00ADR be used as a direct replacement for DM74ALS00AM?

A: Yes. The SN74ALS00ADR maintains identical electrical parameters (supply voltage, output current, input logic levels, propagation delay) and mechanical specifications (14-SOIC surface mount package). Both components are pin-compatible and functionally equivalent within the 74ALS logic family standard.

Q: What is the difference between SN74ALS00ADR and SN74ALS00ANSR?

A: Both parts maintain identical electrical specifications. The primary difference is package width: SN74ALS00ADR uses 14-SOIC (0.154", 3.90mm), while SN74ALS00ANSR uses 14-SO (0.209", 5.30mm). PCB footprint compatibility must be verified before selection.

Q: Why is the DM74ALS00AM classified as obsolete?

A: Obsolete status indicates the manufacturer (onsemi) has discontinued production. Substitute parts from active manufacturers ensure continued component availability and support for new designs and system maintenance.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All Texas Instruments substitute parts (SN74ALS00ADR, SN74ALS00ANSR, SN74ALS00AD) are ROHS3 compliant. The original DM74ALS00AM is REACH unaffected, which is compatible with ROHS3 requirements.

Q: What is the moisture sensitivity level for these components?

A: All parts in this comparison, including the DM74ALS00AM and all substitutes, have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Can SN74ALS00AD be used for new designs?

A: The SN74ALS00AD is classified as last-time-buy, indicating limited future availability. For new designs requiring long-term product support, SN74ALS00ADR (active status) is the preferred selection.
