CD74HC4075EE4 Equivalent & Substitute Parts

Part Overview

The CD74HC4075EE4 is a 3-channel OR gate logic integrated circuit manufactured by Texas Instruments in a 14-pin DIP package. This component is classified as an active product and is currently in production with 775 units in stock. The device performs logical OR operations across three independent channels, each with three inputs, making it suitable for digital logic applications requiring OR gate functionality.

Substitute parts become necessary when the primary part experiences supply constraints, when design requirements mandate alternative manufacturers, or when inventory availability fluctuates. The CD74HC4075E, manufactured by Harris Corporation, provides functional and electrical equivalence under specified conditions.

Substitute Part Grouping Explanation

Substitution eligibility for the CD74HC4075EE4 is determined by strict equivalence across the following parameters:

Critical Matching Parameters:

• Logic type: OR Gate (3 channels, 3 inputs per channel)
• Voltage supply range: 2V to 6V
• Operating temperature range: -55°C to 125°C
• Max propagation delay: 17ns @ 6V, 50pF
• Quiescent current: 2 µA maximum
• Output current specifications: 5.2mA high and low
• Input logic levels: Low 0.5V to 1.8V, High 1.5V to 4.2V
• Package type: 14-DIP (0.300", 7.62mm)
• Mounting type: Through Hole

The CD74HC4075E meets all electrical and mechanical parameters required for direct substitution. Both parts belong to the 74HC logic series and share identical functional specifications, pin configurations, and performance characteristics.

Engineering Selection Recommendations

CD74HC4075EE4 (Primary Selection): The CD74HC4075EE4 is the recommended primary choice for new designs and applications. This part maintains active product status with Texas Instruments, ensuring long-term availability and supply chain stability. The device is ROHS3 compliant, meeting current environmental and regulatory requirements for commercial and industrial applications. Current inventory of 775 units supports immediate procurement needs.

CD74HC4075E (Substitute Selection): The CD74HC4075E is electrically and mechanically equivalent to the primary part and may be selected when CD74HC4075EE4 availability is constrained. However, this part carries obsolete status and is non-compliant with RoHS standards. Use of this substitute should be limited to legacy system maintenance, repair applications, or situations where regulatory compliance is not a design requirement. The higher inventory level (15,787 units) may provide short-term availability advantages in specific supply scenarios.

For new product development, the CD74HC4075EE4 is the appropriate selection. For existing systems currently using CD74HC4075E, direct replacement with CD74HC4075EE4 is supported without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can CD74HC4075E be used as a direct replacement for CD74HC4075EE4?

A: Yes. Both parts share identical electrical specifications, pin configurations, and mechanical dimensions. The 14-DIP package, voltage supply range (2V to 6V), propagation delay (17ns @ 6V, 50pF), and all input/output characteristics are equivalent. Direct substitution is supported at the circuit level.

Q: What is the difference between CD74HC4075EE4 and CD74HC4075E?

A: The primary differences are manufacturer (Texas Instruments vs. Harris Corporation), product status (Active vs. Obsolete), and compliance certification (ROHS3 Compliant vs. RoHS non-compliant). Electrical and mechanical specifications are identical.

Q: Are there any package or pinout differences?

A: No. Both parts use the 14-DIP (0.300", 7.62mm) package with identical through-hole mounting specifications. PCB layout and footprints are interchangeable.

Q: Which part should be selected for new designs?

A: The CD74HC4075EE4 is the appropriate selection for new designs. Active product status ensures continued availability, and ROHS3 compliance meets current regulatory requirements for most commercial and industrial applications.

Q: Can CD74HC4075E be used in applications requiring RoHS compliance?

A: No. The CD74HC4075E is RoHS non-compliant. Applications with RoHS compliance requirements must use the CD74HC4075EE4.

Q: What are the critical parameters for substitution?

A: Substitution is valid when the following parameters match: logic type (OR Gate, 3 channels, 3 inputs), voltage supply range (2V to 6V), operating temperature range (-55°C to 125°C), propagation delay (17ns @ 6V, 50pF), and package type (14-DIP). All parameters are identical between these two parts.
