Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD74HC00M is determined by the following criteria:

Primary Substitution Parameters:

• Logic Type: NAND Gate (4-channel, 2-input configuration)
• Package / Case: 14-SOIC surface mount form factor
• Voltage Supply Range: 2V to 6V minimum compatibility
• Input/Output Logic Levels: Compatible threshold specifications
• Mounting Type: Surface Mount

Substitution Categories:

Direct Equivalents (Identical Specifications): Parts meeting all primary parameters with matching electrical characteristics across voltage supply, quiescent current, output current, propagation delay, and operating temperature range.

Functional Equivalents (Compatible Specifications): Parts with the same logic function and package but with variations in secondary parameters such as quiescent current, propagation delay, or operating temperature range that remain within acceptable tolerance for the 74HC00 logic family.

Manufacturer Variants: Different manufacturers producing the same 74HC00 base product number with identical or near-identical electrical performance and package specifications.

Parameter Comparison

Engineering Selection Recommendations

Tier 1 - Preferred Substitutes (Active Status, Extended Temperature Range):

CD74HC00M96 and MC74HC00ADR2G are the primary recommended substitutes. CD74HC00M96 maintains identical electrical specifications to the original CD74HC00M while offering active product status and improved packaging availability through Cut Tape & Digi-Reel format. MC74HC00ADR2G provides superior performance characteristics with lower quiescent current (1 µA vs 2 µA) and faster propagation delay (13ns vs 15ns), with extended operating temperature range matching the original part (-55°C to 125°C).

Tier 2 - Secondary Substitutes (Active Status, Standard Temperature Range):

SN74HC00DR, MM74HC00M, and MC74HC00ADG are suitable alternatives with active product status. SN74HC00DR offers high inventory availability (178,195 pcs) with standard operating temperature range (-40°C to 85°C). MM74HC00M and MC74HC00ADG provide onsemi manufacturing with active status; MC74HC00ADG offers improved performance metrics (1 µA quiescent current, 13ns propagation delay) with extended temperature range.

Tier 3 - Functional Alternatives (Active Status, Performance Variations):

74HC00D,653 (Nexperia) and 74HC00S14-13 (Diodes Incorporated) are functionally compatible with notable parameter variations. 74HC00D,653 exhibits higher quiescent current (40 µA) but superior propagation delay (7ns). 74HC00S14-13 shows moderate quiescent current increase (20 µA) with standard propagation delay (15ns). Both maintain 2V to 6V supply voltage compatibility and 14-SOIC packaging.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited) rating, matching the original CD74HC00M specifications. REACH status remains unaffected across all alternatives.

Frequently Asked Questions (FAQ)

Q: Can I use SN74HC00DR as a direct replacement for CD74HC00M?

A: SN74HC00DR is functionally compatible with identical electrical specifications (2V-6V supply, 2 µA quiescent current, 15ns propagation delay, 5.2mA output current). The primary difference is operating temperature range: SN74HC00DR operates -40°C to 85°C versus CD74HC00M's -55°C to 125°C. For applications within the -40°C to 85°C range, SN74HC00DR provides direct substitution with active product status and superior inventory availability.

Q: What is the difference between CD74HC00M96 and CD74HC00M?

A: CD74HC00M96 and CD74HC00M are electrically identical with matching specifications across all parameters. The primary distinction is packaging format: CD74HC00M is supplied in Tube packaging while CD74HC00M96 is available in Cut Tape & Digi-Reel format. CD74HC00M96 maintains active product status, making it the preferred choice for new designs and ongoing production.

Q: Why does MC74HC00ADR2G show lower quiescent current and faster propagation delay?

A: MC74HC00ADR2G is manufactured by onsemi using optimized process technology that achieves 1 µA quiescent current (versus 2 µA) and 13ns propagation delay (versus 15ns). These improvements represent enhanced semiconductor manufacturing rather than functional differences. The part remains fully compatible with 74HC00 logic specifications and maintains the same 14-SOIC package and 2V-6V supply voltage range.

Q: Are all substitutes available in 14-SOIC packaging?

A: All listed substitutes are available in 14-SOIC surface mount packaging with 0.154" (3.90mm) width. Packaging format (Tube, Cut Tape & Digi-Reel, or Tape & Reel) varies by manufacturer and part number but does not affect electrical compatibility or PCB mounting.

Q: What is the significance of the extended temperature range (-55°C to 125°C) in CD74HC00M?

A: The extended temperature range indicates the part is qualified for industrial and military applications requiring operation across wider environmental conditions. CD74HC00M, MC74HC00ADR2G, and MC74HC00ADG maintain this extended range. For commercial applications with standard temperature requirements (-40°C to 85°C), standard-range alternatives such as SN74HC00DR provide equivalent functionality.

Q: Can I mix different manufacturers' 74HC00 parts in the same design?

A: Yes. All 74HC00 variants from Texas Instruments, onsemi, Nexperia, Diodes Incorporated, and Fairchild Semiconductor meet the same logic family specifications for NAND gate function, input/output logic levels, and supply voltage range. Mixing manufacturers is permissible provided all parts meet the application's temperature range and performance requirements.
