Substitute Part Grouping Explanation

Substitution for the CD74FCT374M96 is determined by strict equivalence across the following critical parameters: D-Type flip-flop function with 1 element and 8-bit configuration, tri-state non-inverted output type, positive edge trigger operation, 20-SOIC package compatibility, and surface mount mounting type. All substitute parts must maintain the same functional architecture and physical package dimensions to ensure direct replacement capability.

The identified substitute parts are grouped as follows:

Direct Equivalent (Same Manufacturer): CD74FCT374M by Texas Instruments maintains identical electrical specifications and packaging, with the distinction of active product status and tube packaging format.

Manufacturer-Recommended Equivalent (Alternative Source): 74FCT374CTSOG by IDT (Integrated Device Technology Inc) provides functional equivalence within the 74FCT logic family, with enhanced performance characteristics and extended operating temperature range, supplied in bulk packaging.

Parameter Comparison

Engineering Selection Recommendations

CD74FCT374M (Texas Instruments): This direct equivalent is the primary substitute for the obsolete CD74FCT374M96. Both parts share identical electrical specifications, functional architecture, and package dimensions. The CD74FCT374M maintains active product status with ROHS3 compliance, ensuring long-term availability and regulatory alignment. Selection of this part eliminates obsolescence risk while preserving exact electrical and thermal performance characteristics.

74FCT374CTSOG (IDT): This manufacturer-recommended equivalent provides functional substitution with enhanced performance characteristics. The IDT part demonstrates faster propagation delay (5.2ns versus 6.6ns), wider supply voltage tolerance (4.5V ~ 5.5V versus 4.75V ~ 5.25V), and extended operating temperature range (-40°C ~ 85°C versus 0°C ~ 70°C). These improvements support applications requiring broader environmental operating conditions or tighter timing margins. The part maintains identical package geometry and output configuration, enabling direct physical replacement.

Both substitute parts are active products with established supply chains, supporting design continuity and procurement reliability.

Frequently Asked Questions (FAQ)

Q: Can the CD74FCT374M directly replace the CD74FCT374M96?

A: Yes. The CD74FCT374M is a direct equivalent with identical electrical specifications, functional configuration, and 20-SOIC package dimensions. The primary distinction is product status (active versus obsolete) and packaging format (tube versus standard).

Q: What are the key differences between the Texas Instruments and IDT substitutes?

A: Both parts maintain functional equivalence as D-Type 8-bit flip-flops with tri-state outputs in 20-SOIC packages. The IDT 74FCT374CTSOG offers improved propagation delay (5.2ns), wider supply voltage range (4.5V ~ 5.5V), and extended temperature range (-40°C ~ 85°C). The Texas Instruments CD74FCT374M preserves exact electrical specifications of the original part.

Q: Are package dimensions identical across all three parts?

A: Yes. All three parts use the 20-SOIC (0.295", 7.50mm Width) package with surface mount mounting type, ensuring physical interchangeability on printed circuit boards.

Q: Which substitute is recommended for new designs?

A: The CD74FCT374M (Texas Instruments) is recommended for designs requiring exact electrical equivalence. The 74FCT374CTSOG (IDT) is suitable for applications benefiting from enhanced performance margins and extended operating temperature range.

Q: Are both substitutes RoHS compliant?

A: The CD74FCT374M is ROHS3 compliant. RoHS compliance status for the 74FCT374CTSOG is not specified in available documentation.
