Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74HCT86PW,112 is determined by the following critical parameters:

• Logic Function: XOR (Exclusive OR) with 4 channels and 2 inputs per channel
• Package Type: 14-TSSOP surface mount package with identical physical dimensions
• Supply Voltage Compatibility: Operating voltage range must encompass or exceed the original 4.5V ~ 5.5V specification
• Output Drive Capability: Output current ratings (4mA high/low) must be maintained
• Input Logic Levels: Threshold voltages (0.8V low, 2V high) must be compatible
• Operating Temperature Range: Must support the -40°C ~ 125°C operating window
• Compliance Standards: RoHS3 compliance and MSL rating must be equivalent or superior

The MC74HCT86ADTR2G qualifies as a direct substitute based on matching all functional and mechanical parameters while offering improved electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The MC74HCT86ADTR2G is a qualified substitute for the obsolete 74HCT86PW,112. Selection is supported by the following factors:

• Functional Equivalence: Identical XOR logic configuration with matching pin count and package footprint
• Enhanced Performance: Reduced propagation delay (20ns vs. 32ns) and lower quiescent current (1 µA vs. 2 µA) provide performance improvement
• Expanded Operating Range: Supply voltage range of 2V ~ 6V encompasses the original 4.5V ~ 5.5V specification, providing design flexibility
• Extended Temperature Coverage: Operating range of -55°C ~ 125°C exceeds the original -40°C ~ 125°C specification
• Active Product Status: MC74HCT86ADTR2G is actively manufactured by onsemi, ensuring long-term availability and supply chain continuity
• Compliance Alignment: Both parts maintain ROHS3 compliance and MSL 1 rating, with identical electrical interface specifications

Frequently Asked Questions (FAQ)

Q: Can the MC74HCT86ADTR2G be used as a direct replacement for the 74HCT86PW,112?

A: Yes. Both parts share identical logic function, pin configuration, and 14-TSSOP package dimensions. The MC74HCT86ADTR2G meets or exceeds all electrical specifications of the original part.

Q: What are the key differences between these two parts?

A: The MC74HCT86ADTR2G offers improved performance with faster propagation delay (20ns vs. 32ns), lower quiescent current (1 µA vs. 2 µA), and a wider supply voltage range (2V ~ 6V vs. 4.5V ~ 5.5V). The onsemi part is actively manufactured, whereas the Nexperia part is obsolete.

Q: Are the input and output logic levels identical?

A: Yes. Both parts specify identical input logic thresholds (0.8V low, 2V high) and output drive capability (4mA high/low), ensuring direct functional compatibility.

Q: Does the package footprint match exactly?

A: Yes. Both parts use the 14-TSSOP package with identical dimensions of 0.173" × 4.40mm width, allowing direct PCB footprint compatibility without layout modifications.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. Compliance certifications are equivalent.

Q: What is the operating temperature range difference?

A: The MC74HCT86ADTR2G supports -55°C ~ 125°C, which extends the lower temperature limit by 15°C compared to the original part's -40°C ~ 125°C range, providing broader environmental coverage.
