Parameter Comparison

Engineering Selection Recommendations

The CD74AC175M96 from Texas Instruments is a qualified substitute for the obsolete 74AC175SJX. The substitute part maintains identical functional specifications, pin configuration, and output characteristics required for direct replacement in 16-SOIC surface mount applications.

The CD74AC175M96 offers the advantage of active product status, ensuring long-term availability and supply chain continuity. The part is ROHS3 compliant and carries the same REACH unaffected and EAR99 export classification status as the original component.

Physical package dimensions differ slightly between the two parts (5.30mm versus 3.90mm width), which may require PCB layout verification for space-constrained applications. Both parts maintain identical pin counts, spacing, and electrical interface requirements for 16-SOIC packages.

The substitute part demonstrates superior quiescent current performance (8 µA versus 40 µA) and extended operating temperature range (-55°C ~ 125°C versus -40°C ~ 85°C), providing enhanced performance characteristics for demanding applications.

Frequently Asked Questions (FAQ)

Q: Can the CD74AC175M96 directly replace the 74AC175SJX without PCB modifications?

A: The CD74AC175M96 maintains identical pin configuration and electrical interface specifications. Physical package width differs (3.90mm versus 5.30mm), requiring verification that PCB footprint accommodates the substitute part dimensions. Pin-to-pin compatibility is confirmed for direct functional replacement.

Q: What are the key differences between these two parts?

A: Both parts share identical logic function, pin count, and output specifications. The CD74AC175M96 provides lower quiescent current (8 µA versus 40 µA), higher maximum operating temperature (125°C versus 85°C), and active product status. Clock frequency specification differs (100 MHz versus 244 MHz), and propagation delay is slightly higher (12.2 ns versus 9.5 ns).

Q: Is the CD74AC175M96 suitable for high-temperature applications?

A: The CD74AC175M96 operates across -55°C ~ 125°C, exceeding the original 74AC175SJX range of -40°C ~ 85°C. This extended temperature specification supports applications requiring elevated operating temperatures.

Q: Are there compliance or regulatory differences between these parts?

A: Both parts carry identical REACH unaffected status and EAR99 export classification. The CD74AC175M96 includes ROHS3 compliance certification. Both parts maintain unlimited moisture sensitivity level (MSL 1) classification.

Q: What is the significance of the different package widths?

A: Both parts use 16-SOIC surface mount packages with identical pin spacing and configuration. The width difference (5.30mm versus 3.90mm) reflects different manufacturing standards. PCB footprint verification is necessary to confirm the substitute part fits within existing board layout constraints.
