Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 74ACT175SCX are identified based on strict electrical and mechanical compatibility criteria. The following parameters must align for valid substitution:

• Series designation (74ACT)
• Functional type (D-Type flip-flop)
• Configuration (1 element, 4-bit)
• Output type (Complementary)
• Trigger mechanism (Positive Edge)
• Package form factor (16-SOIC with 0.154" width, 3.90mm)
• Supply voltage range (4.5V ~ 5.5V)
• Mounting type (Surface Mount)

The CD74ACT175M96 manufactured by Texas Instruments meets all these criteria, providing functional and mechanical equivalence while offering active product status and enhanced operational specifications.

Frequently Asked Questions (FAQ)

Q: Can the CD74ACT175M96 be used as a direct replacement for the 74ACT175SCX?

A: Yes. Both parts share identical functional specifications, electrical parameters, and 16-SOIC package dimensions. Pin-for-pin compatibility is maintained, allowing direct substitution without circuit modification.

Q: What is the significance of the product status difference?

A: The 74ACT175SCX is classified as obsolete, indicating discontinued manufacturing and limited future availability. The CD74ACT175M96 maintains active status, ensuring reliable procurement and manufacturing support for new designs and production runs.

Q: Are there differences in propagation delay between these parts?

A: The CD74ACT175M96 exhibits a maximum propagation delay of 11.5ns at 5V with 50pF load, compared to 11ns for the 74ACT175SCX. This 0.5ns difference falls within acceptable tolerance for most digital logic applications and does not constitute a functional limitation.

Q: Does the extended temperature range of the CD74ACT175M96 affect compatibility?

A: No. The extended operating range (-55°C to 125°C) of the CD74ACT175M96 encompasses the original specification (-40°C to 85°C), ensuring full compatibility across all temperature conditions specified for the original part.

Q: What packaging options are available for the substitute part?

A: The CD74ACT175M96 is supplied in Tape & Reel format, optimized for automated pick-and-place assembly. The 16-SOIC package dimensions remain identical to the original part.

Q: Are there compliance or certification differences?

A: The CD74ACT175M96 carries RoHS3 compliance certification, reflecting current environmental standards. Both parts maintain equivalent REACH and ECCN classifications, ensuring regulatory consistency in procurement and use.
