CD74HC4075MG4 Equivalent & Substitute Parts

Part Overview

The CD74HC4075MG4 is a 3-channel OR gate logic IC manufactured by Texas Instruments in a 14-SOIC surface mount package. This component is classified as discontinued at DiGi Electronics, making equivalent substitute parts necessary for ongoing design support and procurement. The 74HC4075 series provides standard OR gate functionality suitable for digital logic applications requiring multiple independent OR operations within a single integrated circuit.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD74HC4075MG4 is determined by the following criteria:

Core Functional Parameters (Must Match):

• Logic Type: OR Gate
• Number of Circuits: 3
• Number of Inputs: 3
• Voltage Supply Range: 2V to 6V
• Package Type: 14-SOIC (mechanical compatibility)
• Mounting Type: Surface Mount

Electrical Performance Parameters (Must Match or Exceed):

• Max Propagation Delay: 17ns @ 6V, 50pF
• Current - Quiescent (Max): 2 µA
• Current - Output High/Low: 5.2mA / 5.2mA
• Input Logic Levels: Low 0.5V–1.8V, High 1.5V–4.2V

Acceptable Variations:

• Operating Temperature Range: Minimum -40°C acceptable (main part specifies -55°C to 125°C)
• Manufacturer: Different manufacturers within 74HC4075 base product family
• Packaging Format: Tube, Bulk, or Tape & Reel acceptable for same electrical specifications
• RoHS Compliance: ROHS3 compliant preferred; non-compliant parts noted

All three substitute parts meet these criteria and are electrically and mechanically interchangeable with the CD74HC4075MG4.

Parameter Comparison

Engineering Selection Recommendations

For Active Production (Preferred): Select 74HC4075D,653 (Nexperia USA Inc.) or 74HC4075D,652 (NXP Semiconductors). Both are active products with high inventory availability. The 74HC4075D,653 offers ROHS3 compliance and full electrical parameter specification, making it the primary recommendation for new designs and ongoing production requiring regulatory compliance.

For Legacy System Support: CD74HC4075M (Harris Corporation) provides full electrical and thermal specification matching but carries obsolete status and RoHS non-compliance. Use only when legacy system requirements mandate Harris Corporation sourcing or when RoHS exemptions are documented.

Temperature Range Consideration: The 74HC4075D,653 operates to -40°C minimum, which is acceptable for most commercial and industrial applications. If designs require -55°C minimum operation, verify that the reduced temperature range does not violate system specifications before substitution.

Frequently Asked Questions (FAQ)

Q: Can I substitute CD74HC4075MG4 with any of the listed parts? A: Yes. All three substitute parts are electrically and mechanically equivalent. They share identical logic function, pin configuration, package type, and electrical performance within specified parameters.

Q: What is the difference between 14-SOIC and 14-SO packaging? A: Both designations refer to the same 14-pin Small Outline Integrated Circuit package with 0.154" (3.90mm) width. The terms are used interchangeably in industry documentation.

Q: Does RoHS compliance matter for my application? A: RoHS3 compliance is required for products sold in the European Union and many regulated markets. If your application or supply chain requires RoHS compliance, select 74HC4075D,653. If RoHS exemptions are documented for your system, CD74HC4075M is acceptable.

Q: Which substitute has the best availability? A: 74HC4075D,652 (NXP Semiconductors) has the highest inventory at 16,251 pieces. 74HC4075D,653 (Nexperia USA Inc.) offers 8,058 pieces with active product status and ROHS3 compliance.

Q: Are there temperature range differences I should know about? A: The main part and CD74HC4075M specify -55°C to 125°C operation. The 74HC4075D,653 specifies -40°C to 125°C. For applications requiring operation below -40°C, verify system requirements before substitution.

Q: Can I mix different manufacturers in the same design? A: Yes. All parts meet identical electrical specifications and pin configurations. Mixed sourcing is acceptable from a functional standpoint, though single-source qualification may be preferred for production consistency.
