Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 74LVC14ADR2G is determined by the following critical parameters:

Functional Equivalence: Both the main part and substitute must operate as 6-channel inverters with Schmitt trigger functionality.

Logic Family Compatibility: The substitute part must belong to the 74LVC or 74LCX logic families, which share compatible voltage levels and switching characteristics.

Package Compatibility: Both parts must use the 14-SOIC package format to ensure direct pin-for-pin compatibility in existing PCB layouts.

Electrical Specifications: Supply voltage range, input/output logic levels, and propagation delay characteristics must fall within acceptable operating parameters for the application.

Regulatory Compliance: Both parts must maintain ROHS3 compliance and REACH unaffected status to satisfy current manufacturing and environmental standards.

The MC74LCX14DR2G qualifies as a substitute based on these criteria, offering active product status while maintaining functional and electrical compatibility with the obsolete 74LVC14ADR2G.

Engineering Selection Recommendations

Primary Substitute: MC74LCX14DR2G

The MC74LCX14DR2G is the recommended substitute for the obsolete 74LVC14ADR2G. Both components are manufactured by onsemi and share identical package configurations (14-SOIC), functional architecture (6-channel inverter with Schmitt trigger), and regulatory compliance status (ROHS3 Compliant, REACH Unaffected, EAR99 classification).

The critical advantage of the MC74LCX14DR2G is its active product status, ensuring long-term availability and supply chain continuity. The component is available in Tape & Reel packaging, which is standard for production environments.

Both parts maintain identical HTSUS classification (8542.39.0001) and export control designations, confirming their functional and regulatory equivalence. The MC74LCX14DR2G operates within the 74LCX logic family, which is a direct evolution of the 74LVC series with enhanced performance characteristics while maintaining backward compatibility in standard applications.

For designs currently using the 74LVC14ADR2G, direct substitution with the MC74LCX14DR2G requires no PCB modifications, as pin assignments and package footprints are identical.
