CD74AC175M Equivalent & Substitute Parts

Part Overview

The CD74AC175M is a D-Type flip-flop logic integrated circuit manufactured by Texas Instruments, designed for 4-bit positive edge-triggered applications. This component functions as a master reset flip-flop with complementary outputs and operates across a wide supply voltage range of 1.5V to 5.5V. The part is currently discontinued at DiGi Electronics, making identification of suitable substitutes essential for ongoing design support and production continuity. The CD74AC175M96 serves as the direct functional equivalent, offering identical electrical and mechanical specifications with active product status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD74AC175M is determined by strict equivalence across all electrical and mechanical parameters. The primary substitution criterion is functional and pin-level compatibility within the 74AC logic family, combined with identical packaging specifications. The CD74AC175M96 qualifies as a direct substitute based on the following key parameters:

• Identical base product number (74AC175) and series designation (74AC)
• Matching flip-flop configuration: 1 element, 4-bit, D-Type, positive edge-triggered
• Identical electrical specifications: clock frequency, propagation delay, supply voltage range, output current, quiescent current, and input capacitance
• Identical package specification: 16-SOIC (0.154", 3.90mm Width) surface mount
• Matching operating temperature range: -55°C ~ 125°C
• Equivalent compliance certifications: ROHS3 Compliant, REACH Unaffected, MSL 1

The only distinction between the main part and substitute is packaging format (tube versus tape & reel) and product status (discontinued versus active).

Parameter Comparison

Engineering Selection Recommendations

The CD74AC175M96 is the direct substitute for the CD74AC175M. Both parts are manufactured by Texas Instruments and share identical electrical specifications, pin configuration, and package dimensions. The CD74AC175M96 is currently in active production status, whereas the CD74AC175M is discontinued, making the CD74AC175M96 the appropriate selection for new designs and ongoing production requirements.

Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for industrial and commercial applications. The packaging difference (tape & reel versus tube) reflects distribution format only and does not affect component functionality or performance. Selection between these parts should be based on procurement requirements and supply chain availability, with the CD74AC175M96 recommended for applications requiring active product support and guaranteed long-term availability.

Frequently Asked Questions (FAQ)

Q: Can the CD74AC175M96 be used as a direct replacement for the CD74AC175M?

A: Yes. The CD74AC175M96 is a direct functional and pin-level equivalent. All electrical parameters, operating characteristics, and package specifications are identical. The only differences are product status (active versus discontinued) and packaging format (tape & reel versus tube).

Q: What is the difference between the CD74AC175M and CD74AC175M96?

A: The CD74AC175M is supplied in tube packaging and is discontinued. The CD74AC175M96 is supplied in tape & reel format and maintains active production status. Electrical and mechanical specifications are identical.

Q: Are there any compatibility concerns when substituting the CD74AC175M96 for the CD74AC175M?

A: No compatibility concerns exist. Both parts are pin-for-pin compatible with identical 16-SOIC package dimensions (0.154", 3.90mm width). PCB layouts, schematic connections, and circuit performance remain unchanged.

Q: What parameters determine substitution eligibility for the CD74AC175M?

A: Substitution is determined by matching the base product number (74AC175), flip-flop configuration (1 element, 4-bit, D-Type, positive edge-triggered), electrical specifications (clock frequency, propagation delay, supply voltage, output current, quiescent current), package type (16-SOIC surface mount), and operating temperature range (-55°C ~ 125°C).

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

A: Yes. The CD74AC175M96 operates across the full temperature range of -55°C to 125°C (TA), matching the CD74AC175M specification and supporting industrial and automotive temperature requirements.

Q: What is the significance of the packaging format difference?

A: Packaging format (tube versus tape & reel) affects only procurement and assembly processes. Tape & reel format is standard for automated pick-and-place assembly, while tube packaging is used for manual handling or lower-volume applications. Component performance and functionality are unaffected.
