74HC00N NAND Gate IC Equivalent & Substitute Parts

Part Overview

The 74HC00N is a quad 2-input NAND gate logic IC manufactured by NXP USA Inc., housed in a 14-DIP package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The 74HC00 series represents a standard logic family with multiple manufacturer sources, enabling direct functional replacement across compatible applications.

Substitute Part Grouping Explanation

Substitution of the 74HC00N is determined by strict equivalence across the following criteria:

• Logic Function: All substitute parts must implement quad 2-input NAND gate logic
• Pin Configuration: All parts use 14-DIP package with identical pinout
• Electrical Characteristics: Supply voltage range (2V ~ 6V), output current (5.2mA), and input logic levels must match or exceed the main part specifications
• Package Compatibility: 14-DIP through-hole mounting ensures mechanical interchangeability

The three substitute parts listed—CD74HC00E, SN74HC00N, and TC74HC00APF—all satisfy these core substitution criteria. Variations in quiescent current, propagation delay, and operating temperature ranges represent performance differences within the 74HC00 family but do not prevent functional substitution.

Engineering Selection Recommendations

Primary Recommendation: SN74HC00N (Texas Instruments)

The SN74HC00N is the preferred substitute based on active product status and ROHS3 compliance. This part ensures long-term availability and regulatory alignment for new designs. Operating temperature range of -40°C ~ 85°C covers standard industrial applications.

Secondary Recommendation: TC74HC00APF (Toshiba Semiconductor)

The TC74HC00APF offers superior performance characteristics, including the lowest quiescent current (1 µA) and fastest propagation delay (13ns @ 6V, 50pF). ROHS3 compliance and active product status support procurement continuity. Operating temperature range matches the SN74HC00N.

Alternative: CD74HC00E (Harris Corporation)

The CD74HC00E provides the widest operating temperature range (-55°C ~ 125°C), suitable for extended temperature applications. However, RoHS non-compliance and obsolete status limit suitability for new designs requiring regulatory certification.

Frequently Asked Questions (FAQ)

Q: Can the 74HC00N be directly replaced with any of these substitute parts?

A: Yes. All substitute parts implement identical logic function (quad 2-input NAND gate), use the same 14-DIP package, and operate within the specified voltage supply range (2V ~ 6V). Pin-for-pin replacement is possible without circuit modification.

Q: What are the key differences between the substitute parts?

A: Differences exist in quiescent current consumption, propagation delay, operating temperature range, and product status. The SN74HC00N and TC74HC00APF are active products with ROHS3 compliance. The CD74HC00E is obsolete and RoHS non-compliant. Propagation delay varies from 7ns (74HC00N) to 15ns (CD74HC00E and SN74HC00N), though all values remain within acceptable logic timing margins for standard applications.

Q: Which substitute part should I select for new designs?

A: Select either SN74HC00N (Texas Instruments) or TC74HC00APF (Toshiba Semiconductor). Both are active products with ROHS3 compliance. The TC74HC00APF offers superior power efficiency and faster propagation delay, while the SN74HC00N provides broader market availability.

Q: Are there package compatibility concerns?

A: No. All parts use 14-DIP (0.300", 7.62mm) through-hole packaging with identical pinout. Board-level replacement requires no layout modifications.

Q: Does operating temperature range affect substitution?

A: Operating temperature range affects application suitability but not functional substitution. The 74HC00N supports -40°C ~ 125°C. The CD74HC00E extends to -55°C for low-temperature applications. The SN74HC00N and TC74HC00APF limit to -40°C ~ 85°C, suitable for standard industrial and commercial temperature ranges.

Q: What compliance certifications should I verify?

A: For new designs, confirm ROHS3 compliance and active product status. The SN74HC00N and TC74HC00APF meet both criteria. The CD74HC00E is RoHS non-compliant and obsolete, limiting use to legacy system maintenance or applications without regulatory requirements.
