Substitute Part Grouping Explanation

Substitution of the 74HCT366D,652 is determined by the following critical parameters:

• Logic Function: Buffer, Inverting with 1 element and 6 bits per element
• Output Configuration: 3-State output capability
• Package Compatibility: 16-SOIC surface mount package with 0.154" (3.90mm) width
• Voltage Supply Range: Minimum 4.5V operation required for direct substitution
• Output Current Capability: Minimum 6mA per output
• Temperature Range: Minimum -40°C to 125°C operating range
• Series Compatibility: 74HCT logic family

The MC74HCT366ADR2G from onsemi meets all substitution criteria through functional equivalence in logic type, pin configuration, package geometry, and electrical performance within the specified operating envelope.

Parameter Comparison

Engineering Selection Recommendations

The MC74HCT366ADR2G is a direct functional substitute for the obsolete 74HCT366D,652. Both components are ROHS3 compliant and carry MSL Level 1 ratings, ensuring equivalent environmental and regulatory compliance. The onsemi part demonstrates superior electrical performance with increased output current capability (7.8mA versus 6mA) and an extended supply voltage range (2V ~ 6V versus 4.5V ~ 5.5V), providing enhanced operational flexibility. The onsemi component maintains active product status, ensuring long-term availability and supply chain continuity compared to the obsolete Nexperia part. Identical package geometry and pin configuration enable direct PCB-level replacement without layout modification.

Frequently Asked Questions (FAQ)

Q: Can the MC74HCT366ADR2G replace the 74HCT366D,652 in existing designs?

A: Yes. Both components share identical logic function, pin configuration, and 16-SOIC package dimensions. The onsemi part's expanded voltage range and increased output current provide equivalent or superior performance in all operating conditions specified for the original part.

Q: What is the difference between the Tube and Tape & Reel packaging options?

A: Tube packaging (74HCT366D,652) is used for lower-volume applications and manual assembly processes. Tape & Reel packaging (MC74HCT366ADR2G) is standard for automated pick-and-place manufacturing. Both contain identical die and electrical specifications; packaging selection depends on production volume and assembly methodology.

Q: Are there any temperature range limitations when substituting?

A: No. The MC74HCT366ADR2G operates across -55°C to 125°C, which encompasses the original part's -40°C to 125°C range. Applications requiring the full -55°C lower limit benefit from the onsemi substitute.

Q: Does the higher output current of the MC74HCT366ADR2G affect circuit design?

A: No negative impact. The 7.8mA output current of the onsemi part exceeds the 6mA requirement of the original design, providing additional drive capability without requiring circuit modifications.

Q: Are both parts RoHS compliant?

A: Yes. Both the 74HCT366D,652 and MC74HCT366ADR2G are ROHS3 compliant with MSL Level 1 ratings, meeting identical environmental and regulatory standards.
