Substitute Part Grouping Explanation

Substitute parts for the SN74HC368DR are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Functional Parameters:

• Logic Type: Buffer, Inverting (must match exactly)
• Number of Elements: 2 (must match exactly)
• Number of Bits per Element: 2, 4 (Hex) (must match exactly)
• Output Type: 3-State (must match exactly)
• Current - Output High, Low: 7.8mA, 7.8mA (must match exactly)
• Voltage - Supply: 2V ~ 6V (must match exactly)

Mechanical Parameters:

• Package / Case: 16-SOIC (0.154", 3.90mm Width) (must match exactly)
• Mounting Type: Surface Mount (must match exactly)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (must match exactly)
• Moisture Sensitivity Level: 1 (Unlimited) (must match exactly)

Substitute parts may differ in operating temperature range and product status while maintaining full electrical and mechanical compatibility. The 74HC series base product number remains consistent across all qualified substitutes.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection - SN74HC368DR (Texas Instruments): Active product status with full availability. Recommended for new designs and production applications requiring long-term supply assurance. Operating temperature range of -40°C to 85°C covers standard industrial applications.

Alternative Selection - 74HC368D,653 (Nexperia USA Inc.): Active product status with extended operating temperature range (-40°C to 125°C). Suitable for applications requiring higher temperature operation within the same functional and mechanical specifications. Equivalent RoHS3 compliance and moisture sensitivity rating.

Legacy Selection - MC74HC368ADR2G (onsemi): Obsolete product status. Electrical and mechanical parameters are identical to active alternatives. Selection of this part should be limited to legacy system maintenance or applications where existing inventory must be utilized. New designs should not incorporate this part number.

All three parts maintain identical functional specifications, electrical performance, and package compatibility, ensuring direct substitution capability based on product availability and application temperature requirements.

Frequently Asked Questions (FAQ)

Q: Can the 74HC368D,653 directly replace the SN74HC368DR in existing designs?

A: Yes. Both parts share identical logic type, element count, bit configuration, output type, current ratings, supply voltage range, package dimensions, and mounting type. The extended operating temperature range of the Nexperia part (-40°C to 125°C versus -40°C to 85°C) provides additional thermal margin without affecting circuit compatibility.

Q: What is the difference between the 16-SOIC and 16-SO package designations?

A: Both designations refer to the same 16-pin Small Outline Integrated Circuit package with 0.154" (3.90mm) width. The package dimensions and pin configuration are identical, ensuring mechanical and electrical compatibility across all three part numbers.

Q: Is the MC74HC368ADR2G suitable for new production designs?

A: No. This part carries obsolete product status and should not be selected for new designs. Use the SN74HC368DR (Texas Instruments) or 74HC368D,653 (Nexperia USA Inc.) for new applications. The onsemi part is appropriate only for legacy system support or existing inventory utilization.

Q: Do all three parts meet the same compliance requirements?

A: Yes. All parts are ROHS3 compliant, REACH unaffected, and carry unlimited moisture sensitivity rating (MSL 1). Compliance certifications are identical across all three manufacturers.

Q: What determines whether a part can substitute for the SN74HC368DR?

A: Substitution is determined by matching the following parameters: logic type (Buffer, Inverting), element count (2), bits per element (2, 4 Hex), output type (3-State), output current (7.8mA high and low), supply voltage range (2V to 6V), package type (16-SOIC 0.154" width), mounting type (Surface Mount), and compliance status (ROHS3, MSL 1). Operating temperature range may vary without affecting substitution eligibility.
