Engineering Selection Recommendations

Standard Industrial Applications: The SN74HCS164DR and SN74HCS264DR are functionally equivalent for standard industrial use. Both parts are Active status products with identical electrical specifications, package dimensions, and compliance certifications. Selection between these two standard-grade parts depends on availability and inventory levels.

Automotive Applications: The SN74HCS164QDRQ1 and SN74HCS264QDRQ1 are qualified for automotive applications under AEC-Q100 certification. These parts maintain all electrical and mechanical equivalence to standard-grade versions while meeting automotive reliability and qualification requirements. Use automotive-qualified variants (QDRQ1 suffix) when designs require AEC-Q100 compliance or automotive-grade component specifications.

Compliance Considerations: All substitute parts maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), ensuring compatibility with standard manufacturing and storage conditions. REACH status is unaffected across all variants.

Frequently Asked Questions (FAQ)

Q: Can SN74HCS164DR be directly replaced with SN74HCS264DR? A: Yes. Both parts are standard-grade shift registers with identical electrical parameters, supply voltage range (2V ~ 6V), operating temperature range (-40°C ~ 125°C), and 14-SOIC package dimensions. Direct substitution is supported for applications not requiring automotive qualification.

Q: What is the difference between standard-grade and automotive-qualified variants? A: Automotive-qualified parts (QDRQ1 suffix) include AEC-Q100 certification and are qualified for automotive applications. Standard-grade parts (DR suffix) are suitable for industrial applications. All variants maintain identical electrical specifications and package dimensions.

Q: Are automotive-qualified parts compatible with standard industrial applications? A: Yes. Automotive-qualified parts (SN74HCS164QDRQ1 and SN74HCS264QDRQ1) maintain full electrical and mechanical compatibility with standard industrial applications while providing additional automotive qualification.

Q: What determines substitutability between these shift register parts? A: Substitutability is determined by matching logic type (Shift Register), bit width (8-bit), function (Serial to Parallel), output type (Push-Pull), supply voltage range (2V ~ 6V), operating temperature range (-40°C ~ 125°C), and package type (14-SOIC surface mount). All identified substitutes meet these criteria.

Q: Is the 14-SOIC package identical across all variants? A: Yes. All parts use the 14-SOIC package with 0.154" (3.90mm) width. Package dimensions and pin configurations are identical, enabling direct PCB-level substitution.

Q: What is the moisture sensitivity level for these parts? A: All variants have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage, handling, or manufacturing processes.

Q: Are all variants RoHS3 compliant? A: Yes. All substitute parts maintain ROHS3 compliance and REACH unaffected status.
