Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 74HC366D,652 are qualified based on the following critical parameters:

• Logic Type: Buffer, Inverting (identical function)
• Number of Elements: 1 (identical configuration)
• Number of Bits per Element: 6 (identical bit width)
• Output Type: 3-State (identical output capability)
• Current - Output High, Low: 7.8mA, 7.8mA (identical drive capability)
• Voltage - Supply: 2V ~ 6V (identical supply range)
• Package / Case: 16-SOIC (identical physical footprint)
• Mounting Type: Surface Mount (identical mounting method)

Substitutes are grouped into two categories: direct equivalents (CD74HC366M, CD74HC366M96) and parametric equivalents with automotive qualification (CD74HC366QDRQ1).

Parameter Comparison

Engineering Selection Recommendations

CD74HC366M (Harris Corporation): This part is a direct functional equivalent with identical electrical parameters and 16-SOIC packaging. However, it carries obsolete product status and RoHS non-compliance, making it unsuitable for new designs requiring regulatory compliance.

CD74HC366M96 (Texas Instruments): This part is a direct functional equivalent with active product status and ROHS3 compliance. It provides the widest operating temperature range (-55°C ~ 125°C) and is available in Cut Tape and Digi-Reel packaging formats. This is the primary recommendation for standard applications.

CD74HC366QDRQ1 (Texas Instruments): This part is a parametric equivalent with automotive-grade qualification (AEC-Q100) and active product status. It maintains the original operating temperature range (-40°C ~ 125°C) and ROHS3 compliance. This part is specified for automotive and mission-critical applications requiring AEC-Q100 certification.

Frequently Asked Questions (FAQ)

Q: Can CD74HC366M96 replace 74HC366D,652 in existing designs? A: Yes. CD74HC366M96 is functionally equivalent with identical logic type, bit configuration, output type, drive current, and supply voltage. The 16-SOIC package footprint is identical, enabling direct PCB substitution.

Q: What is the difference between CD74HC366M96 and CD74HC366QDRQ1? A: Both are Texas Instruments parts with active status and ROHS3 compliance. CD74HC366QDRQ1 includes automotive-grade qualification (AEC-Q100) and maintains the original -40°C ~ 125°C operating range. CD74HC366M96 extends the lower temperature limit to -55°C. Select CD74HC366QDRQ1 for automotive applications; CD74HC366M96 for standard industrial use.

Q: Why is CD74HC366M not recommended despite being a direct equivalent? A: CD74HC366M is obsolete and RoHS non-compliant. For new designs and procurement, active, compliant alternatives (CD74HC366M96 or CD74HC366QDRQ1) are preferred to ensure long-term availability and regulatory compliance.

Q: Are all substitute parts available in the same packaging? A: All substitute parts use 16-SOIC surface mount packaging with identical 0.154" (3.90mm) width. Packaging format differs by supplier: CD74HC366M and CD74HC366M96 are available in Tube and Cut Tape/Digi-Reel respectively; CD74HC366QDRQ1 is supplied in Tape & Reel format.

Q: What are the key parameters that determine substitutability? A: Logic type (Buffer, Inverting), element count (1), bit width (6), output type (3-State), drive current (7.8mA), supply voltage (2V ~ 6V), and package (16-SOIC) must remain identical. Operating temperature range and compliance certifications may vary based on application requirements.
