Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74ABT02PW,112 is determined by the following critical parameters:

Functional Equivalence: Logic type (NOR Gate), number of circuits (4), and number of inputs per circuit (2) must remain identical.

Electrical Compatibility: Supply voltage range (4.5V ~ 5.5V), input logic levels (Low: 0.8V, High: 2V), and operating temperature range (-40°C ~ 85°C) must be maintained or exceeded.

Physical Compatibility: Package type (14-TSSOP) and mounting method (Surface Mount) must be identical to ensure direct PCB replacement without layout modifications.

Regulatory Compliance: RoHS3 compliance and REACH unaffected status must be preserved for supply chain and regulatory requirements.

The MC74ACT02DTR2G meets all substitution criteria as an active product alternative with identical logic configuration, package, and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The MC74ACT02DTR2G is a direct functional substitute for the 74ABT02PW,112. Both components share identical logic configuration, supply voltage specifications, input logic thresholds, and package geometry. The substitute part is currently in active production status, ensuring long-term availability and supply chain stability compared to the obsolete 74ABT02PW,112.

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for new designs and system updates. The MC74ACT02DTR2G demonstrates improved quiescent current characteristics (4 µA versus 50 µA) and higher output drive capability (24mA versus 15mA/20mA), providing performance advantages in power-sensitive and high-load applications.

The propagation delay difference (9.5ns versus 3.7ns) must be evaluated within the context of specific system timing requirements. Applications with critical timing constraints below 9.5ns may require additional analysis or alternative solutions.

Frequently Asked Questions (FAQ)

Q: Can the MC74ACT02DTR2G directly replace the 74ABT02PW,112 on existing PCBs?

A: Yes. Both components use the 14-TSSOP package with identical pin assignments and electrical specifications for supply voltage, input logic levels, and operating temperature range. No PCB layout modifications are required.

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

A: The primary differences are product status (obsolete versus active), quiescent current consumption (50 µA versus 4 µA), output drive current (15mA/20mA versus 24mA), and propagation delay (3.7ns versus 9.5ns). The MC74ACT02DTR2G offers lower power consumption and higher output drive capability.

Q: Are there timing considerations when substituting these parts?

A: The MC74ACT02DTR2G has a longer maximum propagation delay (9.5ns) compared to the 74ABT02PW,112 (3.7ns). Applications with timing-critical signal paths operating near the 3.7ns specification should evaluate whether the 9.5ns delay is acceptable for system performance.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both the 74ABT02PW,112 and MC74ACT02DTR2G are ROHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic component procurement and deployment.

Q: Which part should be selected for new designs?

A: The MC74ACT02DTR2G is the appropriate choice for new designs due to its active product status, ensuring availability, technical support, and long-term supply chain continuity. The 74ABT02PW,112 should be reserved for legacy system maintenance only.
