CD74HC02M96G4 NOR Gate IC Equivalent & Substitute Parts

Part Overview

The CD74HC02M96G4 is a 4-channel 2-input NOR gate logic IC manufactured by Texas Instruments in 14-SOIC surface mount packaging. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The CD74HC02M96G4 operates across a 2V to 6V supply voltage range and is suitable for general-purpose logic applications requiring NOR gate functionality. Substitute parts must maintain identical logic configuration, electrical performance within specified tolerances, and compatible packaging to ensure direct replacement capability.

Substitute Part Grouping Explanation

Substitution of the CD74HC02M96G4 is determined by strict equivalence across the following critical parameters:

Logic configuration: 4-channel, 2-input NOR gate
Voltage supply range: 2V ~ 6V minimum
Input/output logic levels and thresholds
Propagation delay performance at specified conditions
Package type: 14-SOIC surface mount
RoHS and environmental compliance status

Substitute parts are grouped into three categories based on their relationship to the main part:

Parametric Equivalents maintain all electrical specifications and differ only in manufacturer or product status. These parts are direct functional replacements.

Direct Manufacturer Equivalents are sourced from alternative manufacturers and meet or exceed the electrical performance of the original part.

Manufacturer Recommended Alternatives are designated by the original manufacturer or cross-reference sources as approved substitutes, including automotive-qualified variants.

Engineering Selection Recommendations

Primary Substitutes (Active Status, Full Temperature Range)

CD74HC02M96 is the direct active equivalent from Texas Instruments with identical electrical specifications and full -55°C to 125°C operating range. This part is recommended as the first choice for direct replacement of the obsolete CD74HC02M96G4.

MC74HC02ADR2G from onsemi provides superior performance with lower quiescent current (1 µA vs. 2 µA) and faster propagation delay (13ns vs. 15ns). This part maintains the full -55°C to 125°C temperature range and is suitable for applications requiring enhanced performance margins.

Secondary Substitutes (Active Status, Limited Temperature Range)

MM74HC02MX from onsemi offers active status with identical electrical specifications but operates within -40°C to 85°C. This part is suitable for applications not requiring the extended low-temperature performance of the original part.

74HC02D,653 from Nexperia USA Inc. is an active alternative with identical electrical specifications. Operating temperature is limited to -40°C to 125°C, making it suitable for applications not requiring operation below -40°C.

Automotive-Qualified Substitute

74HC02D-Q100,118 from Nexperia USA Inc. is AEC-Q100 qualified and suitable for automotive applications. This part maintains identical electrical specifications with -40°C to 125°C operating range and is supplied in Tape & Reel packaging.

Packaging Considerations

MC74HC02ADG is supplied in Tube packaging and maintains full -55°C to 125°C temperature range with superior electrical performance. This variant is suitable for applications where tube packaging is acceptable.

All substitute parts maintain 14-SOIC surface mount package compatibility and ROHS3 compliance status.

Frequently Asked Questions (FAQ)

Q: Can CD74HC02M96 directly replace CD74HC02M96G4?

A: Yes. CD74HC02M96 is the active equivalent with identical electrical specifications, operating temperature range (-55°C to 125°C), and 14-SOIC packaging. This is the recommended primary substitute.

Q: What is the difference between MC74HC02ADR2G and CD74HC02M96?

A: MC74HC02ADR2G offers improved performance with lower quiescent current (1 µA vs. 2 µA) and faster propagation delay (13ns vs. 15ns). Both maintain the full -55°C to 125°C operating range and are functionally equivalent for NOR gate logic applications.

Q: Are the Nexperia 74HC02D,653 and 74HC02D-Q100,118 interchangeable?

A: Both parts are electrically identical and functionally equivalent. The primary difference is packaging: 74HC02D,653 is supplied in Cut Tape & Digi-Reel format, while 74HC02D-Q100,118 is supplied in Tape & Reel format. The Q100,118 variant includes AEC-Q100 automotive qualification.

Q: Can MM74HC02MX be used in applications requiring -55°C operation?

A: No. MM74HC02MX operates within -40°C to 85°C. For applications requiring -55°C operation, use CD74HC02M96, MC74HC02ADR2G, or MC74HC02ADG.

Q: What is the significance of the NLV74HC02ADR2G part?

A: NLV74HC02ADR2G is classified as obsolete and features a slower propagation delay (19ns vs. 15ns). This part is not recommended for new designs and should not be used as a substitute for the CD74HC02M96G4.

Q: Are all substitute parts RoHS3 compliant?

A: All listed substitute parts except MM74HC02M are explicitly RoHS3 compliant. MM74HC02M compliance status is not specified in available documentation.

Q: What packaging options are available for substitutes?

A: Substitute parts are available in Cut Tape & Digi-Reel, Tape & Reel, Tube, and standard Surface Mount packaging. All maintain the 14-SOIC form factor compatible with the original part.
