74HC75D,652 Equivalent & Substitute Parts

Part Overview

The 74HC75D,652 is a D-Type Transparent Latch logic IC manufactured by Nexperia USA Inc., featuring dual 2-bit transparent latch functionality with differential output configuration in a 16-SOIC package. This component is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing design support and procurement continuity. Equivalent parts must maintain identical electrical specifications, package compatibility, and circuit topology to ensure direct substitution without design modification.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 74HC75D,652 are qualified based on the following mandatory electrical and mechanical parameters:

• Logic type and circuit topology (D-Type Transparent Latch, 2:2 configuration)
• Output type (Differential)
• Supply voltage compatibility (2V to 6V range)
• Independent circuit count (2 channels)
• Package form factor (16-SOIC with 0.154" width, 3.90mm)
• Mounting technology (Surface Mount)
• Base product number alignment (74HC75 series)

All identified substitutes maintain these core parameters. Variations in propagation delay (10ns vs. 11ns), operating temperature range extensions, and product status do not preclude substitution when electrical performance requirements are met within specified tolerances.

Parameter Comparison

Engineering Selection Recommendations

CD74HC75M96 (Texas Instruments) is the primary substitute for new designs and procurement. This part maintains full electrical equivalence to the 74HC75D,652, operates in the active product status category, and carries ROHS3 compliance certification. The 10ns propagation delay represents a performance improvement over the original 11ns specification. Extended operating temperature range (-55°C to 125°C) provides additional thermal margin.

CD74HC75MT (Texas Instruments) serves as an alternative substitute with identical electrical specifications and ROHS3 compliance. Last Time Buy status indicates limited future availability; this part is suitable for existing inventory replenishment but not recommended for new long-term procurement strategies.

CD74HC75M (Harris Corporation) is electrically equivalent but carries RoHS non-compliance status and obsolete product classification. This part is not recommended for new designs or applications requiring regulatory compliance documentation.

All three substitutes are pin-compatible and functionally interchangeable within the specified electrical operating parameters.

Frequently Asked Questions (FAQ)

Q: Can CD74HC75M96 directly replace 74HC75D,652 without PCB modification?

A: Yes. Both parts use identical 16-SOIC package geometry (0.154" width, 3.90mm) with surface mount configuration. Pin assignments, electrical characteristics, and functional behavior are equivalent. No PCB layout changes are required.

Q: What is the significance of the 1ns propagation delay difference between 74HC75D,652 (11ns) and substitute parts (10ns)?

A: The substitute parts exhibit faster signal propagation. In timing-critical applications, this represents improved performance. For applications where the original 11ns specification was a maximum constraint, the 10ns performance of substitutes remains compliant. No design recalculation is necessary.

Q: Why is CD74HC75M96 preferred over CD74HC75MT despite identical electrical specifications?

A: CD74HC75M96 maintains Active product status, ensuring long-term availability and manufacturer support. CD74HC75MT is classified as Last Time Buy, indicating that production will cease and future availability cannot be guaranteed. For new designs and ongoing procurement, Active status parts provide supply chain stability.

Q: Are there compliance differences between substitute options?

A: CD74HC75M96 and CD74HC75MT both carry ROHS3 compliance and REACH Unaffected status. CD74HC75M does not meet RoHS requirements. For applications subject to environmental or regulatory compliance mandates, only CD74HC75M96 or CD74HC75MT are acceptable.

Q: What is the operating temperature range impact of substitution?

A: The 74HC75D,652 operates from -40°C to 125°C. All substitutes extend the lower temperature limit to -55°C, providing wider thermal operating margin. This does not create incompatibility; applications designed for the original -40°C to 125°C range remain fully functional with substitute parts.

Q: Can CD74HC75M be used in new designs despite RoHS non-compliance?

A: CD74HC75M is electrically equivalent but does not meet current environmental compliance standards. Use is restricted to legacy system maintenance or applications where RoHS compliance is not required. New designs should specify CD74HC75M96 or CD74HC75MT.
