CD74HC00EE4 Equivalent & Substitute Parts

Part Overview

The CD74HC00EE4 is a NAND Gate IC manufactured by Texas Instruments, featuring 4 channels with 2 inputs per channel in a 14-PDIP package. This logic component operates across a 2V to 6V supply voltage range and is designed for through-hole mounting applications. The part is currently in active production status with full RoHS3 compliance.

Substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when design requirements permit the use of functionally equivalent alternatives from different manufacturers. The CD74HC00E represents a parametrically equivalent option, though with different manufacturer origin and compliance status.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD74HC00EE4 is determined by strict parametric matching across the following criteria:

Functional Parameters: Logic type (NAND Gate), number of circuits (4), and number of inputs per circuit (2) must be identical.

Electrical Parameters: Supply voltage range (2V ~ 6V), quiescent current (2 µA maximum), output current specifications (5.2mA for both high and low states), input logic levels, and propagation delay (15ns @ 6V, 50pF) must match exactly.

Mechanical Parameters: Mounting type (through hole), package designation (14-PDIP), and physical dimensions (14-DIP, 0.300", 7.62mm) must be identical.

Series Designation: Parts must belong to the 74HC logic series to ensure compatibility with existing circuit designs and timing specifications.

The CD74HC00E meets all parametric requirements for substitution, with the exception of RoHS compliance status and product lifecycle stage.

Engineering Selection Recommendations

Primary Selection: CD74HC00EE4 (Texas Instruments) is the recommended choice for new designs and production applications. This part maintains active product status, ensuring long-term availability and manufacturer support. Full RoHS3 compliance satisfies regulatory requirements for commercial and industrial applications.

Alternative Selection: CD74HC00E (Harris Corporation) provides parametric equivalence for applications where supply constraints on the primary part create procurement challenges. However, this part carries obsolete status and RoHS non-compliance designation. Selection of this substitute should be limited to legacy system maintenance, repair operations, or applications where RoHS compliance is not a contractual or regulatory requirement.

Compliance Considerations: Applications subject to RoHS directives, REACH regulations, or customer-mandated environmental compliance standards must use the CD74HC00EE4. The CD74HC00E is unsuitable for such applications due to its non-compliant status.

Inventory Availability: CD74HC00EE4 inventory stands at 945 pieces. CD74HC00E inventory is available at 2200 pieces, providing alternative sourcing when primary part allocation is exhausted.

Frequently Asked Questions (FAQ)

Q: Can CD74HC00E be used as a direct replacement for CD74HC00EE4 in new production?

A: CD74HC00E meets all electrical and mechanical parameters for functional substitution. However, its obsolete status and RoHS non-compliance make it unsuitable for new production unless specific design constraints or regulatory exemptions apply.

Q: What are the critical parameters that determine substitution eligibility?

A: Substitution requires identical logic type (NAND Gate), circuit count (4), input count (2), supply voltage range (2V ~ 6V), output current specifications (5.2mA), propagation delay (15ns @ 6V, 50pF), operating temperature range (-55°C ~ 125°C), and package type (14-PDIP). Any deviation in these parameters disqualifies a part from substitution.

Q: Are there physical compatibility issues between CD74HC00EE4 and CD74HC00E?

A: No. Both parts use identical 14-DIP packaging with 0.300" (7.62mm) pitch. Pin configuration, spacing, and through-hole mounting requirements are identical, ensuring direct PCB compatibility.

Q: Does the Harris Corporation CD74HC00E have different electrical performance?

A: No. All electrical parameters—supply voltage, quiescent current, output current, input logic levels, and propagation delay—are identical between the two parts. Functional performance in circuit operation is equivalent.

Q: Why is RoHS compliance status different between these parts?

A: CD74HC00EE4 represents current-generation manufacturing with RoHS3 compliance. CD74HC00E is an obsolete part manufactured under earlier standards without RoHS compliance. This reflects different manufacturing dates and regulatory environments at time of production.

Q: Can CD74HC00E be used in applications requiring RoHS certification?

A: No. RoHS non-compliance disqualifies CD74HC00E from applications with RoHS contractual or regulatory requirements. Use CD74HC00EE4 for all RoHS-mandated applications.

Q: What is the base product number for these parts?

A: Both CD74HC00EE4 and CD74HC00E are variants of the base product 74HC00, a standard NAND gate logic IC within the 74HC series.
