Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 74AC175SC is determined by strict alignment across the following critical parameters:

Mandatory Matching Criteria:

• Base product number: 74AC175
• Package type: 16-SOIC (0.154", 3.90mm Width)
• Mounting type: Surface Mount
• Function: Master Reset
• Type: D-Type
• Output type: Complementary
• Number of elements: 1
• Number of bits per element: 4
• Trigger type: Positive Edge

The CD74AC175M96 from Texas Instruments satisfies all mandatory criteria, confirming functional and physical compatibility for direct substitution in applications currently using the 74AC175SC.

Parameter Comparison

Engineering Selection Recommendations

The CD74AC175M96 qualifies as a direct functional substitute for the 74AC175SC based on matching core logic specifications and package configuration. The Texas Instruments device offers the advantage of active product status, ensuring continued availability and manufacturing support. ROHS3 compliance of the CD74AC175M96 provides regulatory alignment for applications subject to environmental standards.

Performance trade-offs exist: the CD74AC175M96 exhibits lower clock frequency (100 MHz versus 244 MHz) and increased propagation delay (12.2 ns versus 9.5 ns), while demonstrating superior quiescent current efficiency (8 µA versus 40 µA) and extended operating temperature range (-55°C to 125°C versus -40°C to 85°C). These differences require evaluation against specific application timing and thermal requirements.

Frequently Asked Questions (FAQ)

Q: Can the CD74AC175M96 directly replace the 74AC175SC in existing designs?

A: Yes. Both devices share identical base product number (74AC175), package configuration (16-SOIC), and core logic function (D-Type flip-flop, 1 element, 4-bit, complementary output, positive edge trigger). Physical and functional compatibility is confirmed.

Q: What are the performance differences between these parts?

A: The CD74AC175M96 operates at lower maximum clock frequency (100 MHz versus 244 MHz) and exhibits longer propagation delay (12.2 ns versus 9.5 ns). Conversely, it provides lower quiescent current (8 µA versus 40 µA) and wider operating temperature range (-55°C to 125°C versus -40°C to 85°C). Application-specific timing and thermal constraints determine suitability.

Q: Are there packaging differences?

A: Both devices use 16-SOIC surface mount packages with identical physical dimensions (0.154", 3.90mm width). The 74AC175SC is supplied in tube packaging, while the CD74AC175M96 is supplied in Tape & Reel format. This difference affects procurement and assembly processes but not electrical compatibility.

Q: What is the regulatory compliance status?

A: The CD74AC175M96 is ROHS3 compliant and REACH unaffected. The 74AC175SC status is not specified for RoHS compliance. Both devices are REACH unaffected and carry MSL rating of 1 (unlimited moisture sensitivity).

Q: Why is the 74AC175SC listed as obsolete?

A: Obsolete status indicates the manufacturer (onsemi) has discontinued production. The CD74AC175M96 maintains active status with Texas Instruments, ensuring long-term availability and manufacturing continuity.
