Substitute Part Grouping Explanation

Substitution of the CD74AC174M is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications for:

• Logic function (D-Type Flip Flop with Master Reset)
• Number of elements (1) and bits per element (6)
• Clock frequency (95 MHz maximum)
• Propagation delay (14.6 ns @ 5V, 50pF)
• Trigger type (Positive Edge)
• Output type (Non-Inverted)
• Output current capability (24 mA / 24 mA)
• Supply voltage range (1.5V ~ 5.5V)
• Quiescent current (8 µA)
• Input capacitance (10 pF)
• Operating temperature range (-55°C ~ 125°C)
• Package type (16-SOIC with 0.154" / 3.90mm width)
• Mounting type (Surface Mount)
• Compliance certifications (ROHS3, REACH Unaffected)

The CD74AC174M96 meets all these criteria and is classified as a direct manufacturer equivalent.

Parameter Comparison

Engineering Selection Recommendations

The CD74AC174M96 is the direct equivalent substitute for the discontinued CD74AC174M. Both parts are manufactured by Texas Instruments and share identical electrical specifications, functional characteristics, and compliance certifications. The primary distinction is product status and packaging format: the CD74AC174M is discontinued, while the CD74AC174M96 maintains active production status with Tape & Reel packaging.

For new designs or production continuity, the CD74AC174M96 is the appropriate selection. The part maintains full compatibility with existing circuit designs specified for the CD74AC174M, with no modifications to PCB layout, schematic, or assembly procedures required. Both parts comply with ROHS3 and REACH requirements, ensuring regulatory compliance across manufacturing and end-of-life stages.

Frequently Asked Questions (FAQ)

Q: Can the CD74AC174M96 be used as a direct replacement for the CD74AC174M?

A: Yes. The CD74AC174M96 is electrically and mechanically identical to the CD74AC174M across all specified parameters. No circuit modifications are required for substitution.

Q: What is the difference between CD74AC174M and CD74AC174M96?
