Substitute Part Grouping Explanation

Substitute parts for the DM74ALS652WMX are classified based on strict parameter alignment across the following criteria:

Direct Substitutes maintain identical base product numbers (74ALS652), logic type (non-inverting transceiver), element and bit configurations (1 element, 8 bits per element), output type (3-state), current ratings (15mA/24mA), supply voltage range (4.5V ~ 5.5V), operating temperature (0°C ~ 70°C), and package dimensions (24-SOIC, 0.295" width). These parts differ only in packaging format (tube vs. tape & reel) and manufacturer (Texas Instruments vs. onsemi).

Parametric Equivalents share all electrical and functional parameters with the main part but utilize different base product numbers within the 74ALS series. The SN74ALS646ADWR maintains complete parameter compatibility while representing a variant designation within the same logic family.

All substitute parts are manufactured by Texas Instruments and carry active product status with RoHS3 compliance, contrasting with the obsolete status of the original onsemi component.

Parameter Comparison

Engineering Selection Recommendations

All Texas Instruments substitute parts (SN74ALS652ADW, SN74ALS652A-1DW, SN74ALS652ADWR, and SN74ALS646ADWR) are classified as active products with full RoHS3 compliance, providing regulatory advantage over the obsolete onsemi DM74ALS652WMX. These alternatives maintain complete electrical and functional parameter equivalence, ensuring direct circuit compatibility.

Selection between tube and tape & reel packaging formats depends on procurement and assembly requirements. The SN74ALS652ADW and SN74ALS652A-1DW are supplied in tube packaging, while SN74ALS652ADWR and SN74ALS646ADWR are supplied in tape & reel format. Tape & reel packaging is standard for automated assembly processes, whereas tube packaging is suitable for manual handling and lower-volume applications.

The SN74ALS652ADWR offers the highest current inventory level (2845 pcs), providing supply chain reliability for immediate procurement needs.

Frequently Asked Questions (FAQ)

Q: Can the SN74ALS652ADW directly replace the DM74ALS652WMX in existing designs?

A: Yes. The SN74ALS652ADW maintains identical electrical specifications, including logic type (non-inverting transceiver), element configuration (1 element, 8 bits), output type (3-state), current ratings (15mA/24mA), supply voltage (4.5V ~ 5.5V), operating temperature range (0°C ~ 70°C), and package dimensions (24-SOIC, 0.295" width). The only difference is packaging format (tube vs. 24-SOP) and manufacturer.

Q: What is the difference between tube and tape & reel packaging?

A: Tube packaging (SN74ALS652ADW, SN74ALS652A-1DW) is suitable for manual handling and lower-volume applications. Tape & reel packaging (SN74ALS652ADWR, SN74ALS646ADWR) is designed for automated pick-and-place assembly and is standard for high-volume production. Both formats contain identical components with the same electrical performance.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All Texas Instruments substitute parts carry RoHS3 compliance certification. The original onsemi DM74ALS652WMX does not specify RoHS status.

Q: What is the difference between SN74ALS652ADWR and SN74ALS646ADWR?

A: Both parts are parametric equivalents with identical electrical specifications and package dimensions. The difference lies in the base product number designation (74ALS652 vs. 74ALS646) within the 74ALS logic family. Both maintain complete functional compatibility with the original DM74ALS652WMX.

Q: Which substitute part should be selected for new designs?

A: For new designs, SN74ALS652ADWR is recommended due to active product status, RoHS3 compliance, tape & reel packaging suitable for automated assembly, and highest inventory availability (2845 pcs). This part ensures long-term supply chain stability and regulatory compliance.

Q: Are there any differences in moisture sensitivity between the main part and substitutes?

A: No. All parts, including the original DM74ALS652WMX and all Texas Instruments substitutes, carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.
