Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 74HC75N,652 is determined by strict alignment across the following critical parameters:

Logic Function: Both parts must implement D-Type Transparent Latch architecture with identical 2:2 circuit configuration and differential output topology.

Electrical Specifications: Supply voltage range (2V ~ 6V), output current capability (5.2mA), and propagation delay characteristics must be compatible or superior.

Package Compatibility: 16-DIP through-hole mounting with 0.300" (7.62mm) pitch is mandatory for direct board-level substitution.

Compliance & Certification: RoHS3 compliance and REACH unaffected status ensure regulatory alignment.

The CD74HC75E from Texas Instruments meets all substitution criteria as an active-status alternative within the 74HC logic family.

Parameter Comparison

Engineering Selection Recommendations

The CD74HC75E from Texas Instruments is a direct functional equivalent for the obsolete 74HC75N,652. Selection of the TI alternative provides the following advantages:

Active Product Status: The CD74HC75E maintains active manufacturing and distribution status, ensuring long-term availability and supply chain continuity compared to the NXP obsolete part.

Enhanced Performance: Propagation delay of 10ns versus 11ns provides marginal speed improvement without compromising system timing requirements.

Extended Temperature Range: Operating range of -55°C to 125°C exceeds the original -40°C to 125°C specification, supporting broader environmental deployment scenarios.

Regulatory Compliance: Both ROHS3 compliance and REACH unaffected status are maintained, ensuring no regulatory substitution barriers.

Pinout & Package Alignment: Identical 16-DIP through-hole package eliminates PCB redesign requirements for direct component replacement.

Frequently Asked Questions (FAQ)

Q: Can the CD74HC75E directly replace the 74HC75N,652 without PCB modifications?

A: Yes. Both components use identical 16-DIP through-hole packaging with 0.300" (7.62mm) pitch. Direct socket substitution is possible without PCB layout changes.

Q: Are there functional differences between the NXP and Texas Instruments versions?

A: No. Both implement identical D-Type Transparent Latch logic with 2:2 circuit configuration, differential output, and 5.2mA output current. The CD74HC75E operates 1ns faster (10ns vs 11ns propagation delay).

Q: Does the CD74HC75E meet the same compliance requirements?

A: Yes. The CD74HC75E is ROHS3 compliant and REACH unaffected, matching the original part's regulatory status.

Q: Why is the CD74HC75E recommended over the 74HC75N,652?

A: The 74HC75N,652 is obsolete with limited availability. The CD74HC75E is an active product from a major manufacturer, ensuring reliable supply, technical support, and long-term design continuity.

Q: What is the operating temperature difference, and does it matter?

A: The CD74HC75E operates from -55°C to 125°C versus -40°C to 125°C for the original part. This extended lower temperature range provides additional environmental flexibility for applications requiring operation below -40°C.

Q: Are there any electrical parameter differences that affect circuit design?

A: No. Supply voltage (2V ~ 6V), output current (5.2mA), and independent circuit count (2) are identical. The 1ns propagation delay improvement in the CD74HC75E is negligible for most timing-critical applications.
