Engineering Selection Recommendations

Primary Substitute - 74AHC574D,118 (Nexperia USA Inc.): This part is the recommended primary substitute for the CD74HC564M96. It maintains active product status, ROHS3 compliance, and unlimited MSL rating. The 74AHC574D,118 operates within the overlapping supply voltage range (2V to 5.5V) and provides superior performance characteristics with 115 MHz clock frequency, 10.6ns propagation delay, and 4 µA quiescent current. The primary design consideration is output polarity: the 74AHC574D,118 features tri-state non-inverted output, whereas the CD74HC564M96 has tri-state inverted output. Circuit logic must accommodate this inversion difference.

Secondary Substitutes - MC74HC574ADWG and MC74HC574ADWR2G (onsemi): Both onsemi MC74HC574 variants maintain active product status and full ROHS3 compliance with unlimited MSL rating. These parts operate identically across the 2V to 6V supply range with -55°C to 125°C temperature range, matching the CD74HC564M96 specifications. Output configuration is tri-state non-inverted. Propagation delay is 27ns at 6V with 50pF load, and quiescent current is 4 µA. The MC74HC574ADWG is packaged in Tube format, while MC74HC574ADWR2G uses Cut Tape & Digi-Reel packaging. Both are functionally equivalent and differ only in packaging and distribution format.

Tertiary Substitutes - MC74HC374ADWG and MC74HC374ADWR2G (onsemi): These onsemi MC74HC374 variants are functionally compatible with identical electrical specifications to the MC74HC574 series. Both maintain active product status and ROHS3 compliance. MSL rating is 3 (168 Hours), indicating moisture sensitivity requiring controlled storage conditions. Operating parameters match the MC74HC574 series: 2V to 6V supply, -55°C to 125°C temperature range, 35 MHz clock frequency, 21ns propagation delay, and 4 µA quiescent current. Output configuration is tri-state non-inverted.

Not Recommended - MC74HC377ADWR2G (onsemi): This part carries obsolete product status and is not recommended for new designs. Although it maintains ROHS3 compliance and operates within compatible electrical parameters (2V to 6V supply, -55°C to 125°C temperature range), the obsolete designation indicates discontinued manufacturing and potential supply chain constraints. MSL rating is 3 (168 Hours). Output configuration is non-inverted without tri-state capability, representing a functional limitation compared to the CD74HC564M96.

Frequently Asked Questions (FAQ)

Q: Can the 74AHC574D,118 directly replace the CD74HC564M96 without circuit modifications?

A: The 74AHC574D,118 is electrically compatible and pin-compatible in the 20-SOIC package. However, the output polarity differs: the CD74HC564M96 has inverted tri-state output, while the 74AHC574D,118 has non-inverted tri-state output. Circuit logic must be evaluated to determine if output inversion compensation is required. Supply voltage range differs slightly (74AHC574D,118 maximum is 5.5V versus CD74HC564M96 maximum of 6V).

Q: What is the difference between MC74HC574ADWG and MC74HC574ADWR2G?

A: Both parts are functionally identical with matching electrical specifications. The difference is packaging format: MC74HC574ADWG is supplied in Tube packaging, while MC74HC574ADWR2G uses Cut Tape & Digi-Reel format. Selection depends on assembly process requirements and inventory management preferences.

Q: Why is the MC74HC377ADWR2G marked as obsolete?

A: The MC74HC377ADWR2G carries obsolete product status, indicating Texas Instruments or the original manufacturer has discontinued production. Obsolete parts present supply chain risk and are not recommended for new designs. Active alternatives such as MC74HC574ADWG or MC74HC574ADWR2G should be used instead.

Q: Are all substitute parts ROHS3 compliant?

A: All listed substitute parts are ROHS3 compliant. However, MSL (Moisture Sensitivity Level) ratings differ. The CD74HC564M96 and 74AHC574D,118 have MSL 1 (Unlimited), while onsemi parts (MC74HC374 and MC74HC574 series) have MSL 3 (168 Hours), requiring controlled storage and handling procedures.

Q: What is the temperature operating range difference between substitutes?

A: The CD74HC564M96 and all onsemi substitutes operate across -55°C to 125°C. The 74AHC574D,118 operates across -40°C to 125°C, representing a narrower low-temperature range. Applications requiring operation below -40°C must use the CD74HC564M96 or onsemi alternatives.

Q: Can I use MC74HC374ADWG as a substitute for MC74HC574ADWG?

A: Yes, MC74HC374ADWG and MC74HC574ADWG are functionally equivalent with identical electrical specifications and output configuration (tri-state non-inverted). Both operate across 2V to 6V supply range with -55°C to 125°C temperature range. The primary difference is MSL rating: MC74HC374ADWG has MSL 3 (168 Hours) versus MC74HC574ADWG MSL 3 (168 Hours), making them equivalent in moisture sensitivity requirements.

Q: What is the significance of the 20-SOIC package specification?

A: The 20-SOIC (Small Outline Integrated Circuit) package with 0.295" (7.50mm) width is a standardized surface mount package format. All listed substitutes use identical 20-SOIC package geometry, ensuring mechanical and electrical compatibility with existing PCB layouts and assembly processes. No board redesign is required when substituting between parts with matching 20-SOIC specifications.
