Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD74HC4075PW is determined by strict equivalence across the following parameters:

• Logic Function: Identical 3-channel, 3-input OR gate configuration
• Electrical Specifications: Matching voltage supply range (2V–6V), quiescent current (2 µA max), output current ratings (5.2mA), and propagation delay (17ns @ 6V, 50pF)
• Package Compatibility: 14-TSSOP surface mount package with identical pin configuration
• Thermal Range: Operating temperature range of -55°C to 125°C
• Compliance: ROHS3 compliance and REACH unaffected status

Substitute parts must maintain identical electrical performance and physical compatibility to ensure direct replacement without circuit redesign.

Parameter Comparison

Engineering Selection Recommendations

The CD74HC4075PWR is the direct functional equivalent of the CD74HC4075PW. Both parts share identical electrical characteristics, logic function, and package specifications. The primary distinction is product status and packaging format: the CD74HC4075PWR maintains active status with availability in Cut Tape and Digi-Reel formats, while the CD74HC4075PW is discontinued.

For new designs and ongoing procurement, the CD74HC4075PWR is the appropriate selection. Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings, ensuring compatibility with current manufacturing and environmental standards.

Frequently Asked Questions (FAQ)

Q: Can CD74HC4075PWR directly replace CD74HC4075PW in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The CD74HC4075PWR operates across the same voltage range (2V–6V), maintains identical propagation delay (17ns @ 6V, 50pF), and uses the same 14-TSSOP package. No circuit modifications are required.

Q: What is the difference between the tube and Cut Tape packaging formats?

A: Tube packaging (CD74HC4075PW) is used for lower-volume applications, while Cut Tape and Digi-Reel formats (CD74HC4075PWR) are standard for higher-volume production. The internal component is identical; packaging format affects handling and automated assembly compatibility.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts carry ROHS3 compliance, REACH unaffected status, and identical MSL ratings (1 – Unlimited). They meet the same environmental and regulatory requirements.

Q: Why is the CD74HC4075PW discontinued?

A: The CD74HC4075PWR represents the current active product line for this logic function. Discontinuation of the tube-packaged variant reflects standard industry practice of consolidating product offerings around high-volume packaging formats.

Q: Can I use alternative manufacturers' 74HC4075 parts as substitutes?

A: Substitution depends on exact equivalence of electrical specifications and package compatibility. Any alternative must maintain identical logic function, voltage range, propagation delay, and 14-TSSOP package configuration. Verify all parameters before selection.
