Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SN74HC652DW are classified based on the following critical parameters that determine functional and mechanical compatibility:

Primary Substitution Criteria:

• Logic Type: Transceiver, Non-Inverting
• Number of Elements: 1
• Number of Bits per Element: 8
• Output Type: 3-State
• Voltage - Supply: 2V ~ 6V
• Package / Case: 24-SOIC
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant

Substitution Categories:

MFR Recommended Substitute (Packaging Variant): SN74HC652DWR differs from the main part only in packaging format (Tape & Reel vs. Tube), maintaining identical electrical specifications and active product status.

Parametric Equivalent: SN74HC646DW shares identical electrical parameters, package dimensions, and compliance certifications as the main part, with the same Last Time Buy status.

Cross-Reference Part: 74HC86D,653 is listed as a cross-reference but represents a different logic function (XOR gate) with different pin configuration and package type (14-SOIC), limiting direct substitution capability.

Parameter Comparison

Engineering Selection Recommendations

For Direct Functional Replacement:

SN74HC652DWR is the primary recommended substitute. It maintains all electrical specifications, package dimensions, and compliance requirements identical to the SN74HC652DW. The only difference is packaging format (Tape & Reel vs. Tube). This part carries Active product status, providing extended availability compared to the Last Time Buy status of the original part.

For Parametric Equivalence:

SN74HC646DW provides full parametric compatibility with the SN74HC652DW, including identical electrical performance, 24-SOIC package, and ROHS3 compliance. Both parts share Last Time Buy status. This part is suitable for applications where the specific transceiver configuration of the 74HC646 series meets functional requirements.

For Extended Temperature Range Applications:

74HC86D,653 offers an extended operating temperature range (-40°C to 125°C vs. -40°C to 85°C) and Active product status. However, this part implements XOR logic function with different pin configuration and 14-SOIC package, making it unsuitable as a direct pin-for-pin replacement. Selection of this part requires circuit redesign and is not recommended for direct substitution.

Frequently Asked Questions (FAQ)

Q: Can SN74HC652DWR be used as a direct replacement for SN74HC652DW?

A: Yes. SN74HC652DWR is electrically and mechanically identical to SN74HC652DW. The only difference is packaging format: SN74HC652DWR is supplied in Tape & Reel format while SN74HC652DW is supplied in Tube format. Both parts are pin-for-pin compatible and functionally equivalent.

Q: What is the difference between SN74HC652DW and SN74HC646DW?

A: Both parts are Transceiver, Non-Inverting logic ICs with identical electrical specifications, supply voltage range (2V ~ 6V), output current ratings (7.8mA), operating temperature range (-40°C ~ 85°C), and 24-SOIC package. The primary difference is the base product number designation (74HC652 vs. 74HC646), which reflects different internal transceiver configurations. Both parts are ROHS3 compliant and carry Last Time Buy status.

Q: Why is 74HC86D,653 listed as a substitute if it has different specifications?

A: 74HC86D,653 is listed as a cross-reference part but does not qualify as a direct substitute. This part implements XOR (Exclusive OR) logic rather than Transceiver function, features 4 channels with 2 inputs each rather than 1 element with 8 bits, uses a 14-SOIC package instead of 24-SOIC, and has different output current ratings (5.2mA vs. 7.8mA). Direct substitution would require circuit redesign and is not recommended.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. SN74HC652DWR, SN74HC646DW, and 74HC86D,653 are all ROHS3 compliant, matching the compliance status of the main part SN74HC652DW.

Q: What should I consider when selecting between SN74HC652DWR and SN74HC646DW?

A: Both parts are electrically equivalent and use identical 24-SOIC packages. The selection should be based on availability and internal transceiver configuration requirements. SN74HC652DWR is the recommended choice due to its Active product status, providing longer-term availability compared to the Last Time Buy status of SN74HC646DW.
