Substitute Part Grouping Explanation

Substitution of the SN74LVC14ARGYRG4 is determined by strict equivalence across the following critical parameters:

• Logic configuration: 6-channel inverter with Schmitt trigger inputs
• Electrical specifications: Supply voltage range 1.65V ~ 3.6V, quiescent current 1 µA maximum, output drive 24mA
• Input/output logic levels: Low 0.15V ~ 0.8V, High 1.3V ~ 2V
• Timing performance: 6.2ns maximum propagation delay at 3.3V with 50pF load
• Package format: 14-VFQFN Exposed Pad surface mount
• Temperature range: -40°C ~ 85°C
• Compliance: ROHS3 compliant, MSL 2 rating

The SN74LVC14ARGYR meets all these criteria and is the direct equivalent substitute. The difference between the two part numbers reflects packaging configuration only (ARGYRG4 vs ARGYR), with the substitute available in active production status.

Parameter Comparison

Engineering Selection Recommendations

The SN74LVC14ARGYR is the direct functional and electrical equivalent of the SN74LVC14ARGYRG4. Both parts are manufactured by Texas Instruments with identical electrical specifications, logic configuration, and package format. The primary distinction is product status: the SN74LVC14ARGYRG4 is discontinued at DiGi Electronics, while the SN74LVC14ARGYR maintains active production status with significantly higher inventory availability (120,200 pieces versus 775 pieces).

Both parts maintain ROHS3 compliance and identical MSL 2 ratings, ensuring equivalent environmental and regulatory compliance for applications requiring these certifications. The substitute part is suitable for direct replacement in all applications where the main part was originally specified.

Frequently Asked Questions (FAQ)

Q: Can the SN74LVC14ARGYR directly replace the SN74LVC14ARGYRG4 in existing designs?

A: Yes. Both parts are electrically and functionally identical with matching supply voltage ranges, logic levels, propagation delay, output drive capability, and package format. No circuit modifications are required.

Q: What is the difference between SN74LVC14ARGYRG4 and SN74LVC14ARGYR?

A: The part numbers differ in packaging configuration designation. The ARGYRG4 suffix indicates a specific packaging variant that is now discontinued. The ARGYR variant is the active production equivalent with identical electrical and mechanical specifications.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts carry identical ROHS3 compliance status and MSL 2 moisture sensitivity ratings. They meet the same regulatory and environmental standards.

Q: What is the supply voltage compatibility range for both parts?

A: Both the SN74LVC14ARGYRG4 and SN74LVC14ARGYR operate across 1.65V to 3.6V supply voltage range, supporting applications from low-voltage battery-powered systems to standard 3.3V logic circuits.

Q: Is the 14-VFQFN package identical between both parts?

A: Yes. Both parts use the same 14-VFQFN (4.6x4.6) surface mount package with exposed pad. PCB footprints and assembly processes are identical.

Q: What is the propagation delay specification for signal inversion?

A: Maximum propagation delay is 6.2 nanoseconds at 3.3V supply voltage with a 50pF load for both parts.
