MM74HC00N NAND Gate IC Equivalent & Substitute Parts

Part Overview

The MM74HC00N is a 4-channel 2-input NAND gate logic IC manufactured by onsemi in a 14-MDIP package. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The MM74HC00N operates across a 2V to 6V supply voltage range with low quiescent current and standard propagation delay characteristics typical of 74HC series logic gates. Substitute parts maintain functional equivalence through identical logic configuration, electrical performance parameters, and mechanical compatibility.

Substitute Part Grouping Explanation

Substitute parts for the MM74HC00N are classified based on electrical parameter equivalence and product status. All substitute parts maintain identical logic configuration (4-channel 2-input NAND gate), supply voltage range (2V ~ 6V), output current specifications (5.2mA), and input logic thresholds. The primary substitution criteria are:

• Identical logic function and circuit count
• Matching supply voltage and quiescent current specifications
• Compatible propagation delay characteristics
• Through-hole mounting in 14-DIP package format
• Operating temperature range compatibility

Direct manufacturer substitutes (CD74HC00E, SN74HC00N, SN74HC00NE4) provide full electrical equivalence with the MM74HC00N. The TC74HC00APF from Toshiba offers superior performance characteristics (1 µA quiescent current, 13ns propagation delay) while maintaining functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring direct replacement of the MM74HC00N, the SN74HC00N or SN74HC00NE4 from Texas Instruments are preferred substitutes. Both parts are active products with ROHS3 compliance and identical electrical specifications to the MM74HC00N. These parts provide long-term availability and supply chain stability compared to the obsolete MM74HC00N.

The TC74HC00APF from Toshiba offers enhanced performance characteristics with reduced quiescent current (1 µA versus 2 µA) and faster propagation delay (13ns versus 15ns). This part is suitable for applications where lower power consumption or improved timing margins are beneficial, provided the design accommodates the performance improvement.

The CD74HC00E from Harris Corporation is electrically equivalent but classified as obsolete. This part should not be selected for new designs or long-term production requirements. The extended operating temperature range (-55°C ~ 125°C) of the CD74HC00E may be relevant for specialized applications requiring operation beyond the standard -40°C ~ 85°C range.

All substitute parts maintain mechanical compatibility through identical 14-DIP package format and through-hole mounting, ensuring direct PCB footprint compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the SN74HC00N directly replace the MM74HC00N without circuit modifications?

A: Yes. The SN74HC00N provides direct electrical and mechanical equivalence. All critical parameters including supply voltage range, output current, input logic thresholds, and propagation delay are identical. The 14-DIP package format ensures PCB footprint compatibility.

Q: What is the difference between the TC74HC00APF and other substitutes?

A: The TC74HC00APF offers improved performance with lower quiescent current (1 µA) and faster propagation delay (13ns). These characteristics reduce power consumption and provide tighter timing margins. Electrical compatibility remains unchanged, making it suitable for direct substitution in applications where performance enhancement is acceptable.

Q: Why is the MM74HC00N classified as obsolete?

A: The MM74HC00N is an older product no longer in active production. Active alternatives from major manufacturers (Texas Instruments, Toshiba) provide equivalent functionality with improved compliance certifications and guaranteed long-term availability.

Q: Are there any compliance differences between substitute parts?

A: Yes. The SN74HC00N and SN74HC00NE4 are ROHS3 compliant, while the CD74HC00E is RoHS non-compliant. For applications subject to RoHS requirements, select the SN74HC00N, SN74HC00NE4, or TC74HC00APF. All parts are REACH unaffected or vendor undefined, with no restrictions on use.

Q: Can the CD74HC00E be used in new designs?

A: The CD74HC00E is obsolete and should not be selected for new designs. Active alternatives provide superior supply chain support and compliance certifications. The extended operating temperature range (-55°C ~ 125°C) is the only distinguishing feature; if this range is required, the TC74HC00APF or SN74HC00N should be evaluated for custom temperature specifications.

Q: What is the significance of the 14-DIP package format?

A: The 14-DIP (0.300", 7.62mm) package is a standard through-hole format used across all substitute parts. This ensures mechanical and electrical compatibility without PCB redesign. Pin assignments and spacing are identical across all listed substitutes.
