Parameter Comparison

Engineering Selection Recommendations

The MC74HC597ADTR2G is a qualified substitute for the 74HC597PW,112 based on the following engineering criteria:

Electrical Equivalence: Both parts operate within identical supply voltage ranges (2V ~ 6V) and share identical logic function, bit width, and output characteristics. The MC74HC597ADTR2G provides an extended operating temperature range (-55°C ~ 125°C versus -40°C ~ 125°C), which offers additional thermal margin for demanding applications.

Mechanical Compatibility: Both components use the 16-TSSOP surface mount package with identical footprint dimensions, ensuring direct PCB layout compatibility without redesign.

Compliance & Availability: The MC74HC597ADTR2G maintains ROHS3 compliance and REACH unaffected status, matching the regulatory requirements of the original part. Critically, the substitute is currently in active production status with 3,369 units in stock, whereas the original 74HC597PW,112 is obsolete with limited availability.

Packaging: The MC74HC597ADTR2G is supplied in Tape & Reel (TR) format, standard for high-volume production environments.

Frequently Asked Questions (FAQ)

Q: Can the MC74HC597ADTR2G be used as a direct replacement for the 74HC597PW,112 in existing designs?

A: Yes. Both parts share identical electrical specifications (8-bit shift register, 2V ~ 6V supply, push-pull output), identical package geometry (16-TSSOP), and matching compliance certifications. No circuit modifications are required.

Q: What is the difference in operating temperature range between these parts?

A: The 74HC597PW,112 operates from -40°C to 125°C, while the MC74HC597ADTR2G operates from -55°C to 125°C. The substitute provides a 15°C lower temperature limit, offering extended performance in cold environments.

Q: Are there any packaging differences between these parts?

A: Both parts use the 16-TSSOP surface mount package with identical footprint dimensions (0.173" width, 4.40mm width). The MC74HC597ADTR2G is supplied in Tape & Reel format, which is standard for production assembly.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the 74HC597PW,112 and MC74HC597ADTR2G are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity levels (MSL 1 - Unlimited).

Q: Why is the original part listed as obsolete?

A: The 74HC597PW,112 from Nexperia is no longer in active production. The MC74HC597ADTR2G from onsemi provides equivalent functionality and is currently in active production with available inventory.

Q: Are the functional characteristics identical between these parts?

A: Yes. Both parts are 8-bit shift registers with parallel-to-serial conversion capability, push-pull output stages, and single-element configuration. Electrical performance is equivalent across all specified parameters.
