Substitute Part Grouping Explanation

Substitution of the SN74ALVC04RGYRG4 is determined by strict equivalence across the following critical parameters:

Logic function: 6-channel inverter with single input per channel
Electrical specifications: Supply voltage 1.65V ~ 3.6V, quiescent current 10 µA maximum, output drive 24mA, propagation delay 2.8ns @ 3.3V with 50pF load
Input/output logic levels: Low 0.7V ~ 0.8V, High 1.7V ~ 2V
Operating temperature range: -40°C ~ 85°C
Package: 14-VFQFN Exposed Pad surface mount
Compliance: ROHS3 compliant, MSL 2 (1 Year)

The SN74ALVC04RGYR meets all these criteria and qualifies as a parametric equivalent. The primary distinction is packaging format: the main part uses individual packaging while the substitute is supplied in Tape & Reel (TR) format.

Engineering Selection Recommendations

The SN74ALVC04RGYR is a direct parametric equivalent to the SN74ALVC04RGYRG4. All electrical characteristics, logic function, operating conditions, and compliance certifications are identical. The substitute part carries Active product status, ensuring ongoing availability and supply chain continuity. Both parts maintain ROHS3 compliance and identical MSL ratings. The only operational difference is the packaging format: Tape & Reel (TR) supply versus individual packaging. For production environments utilizing automated assembly equipment, the Tape & Reel format is standard and preferred. For prototype or low-volume applications, individual packaging may be sourced separately or the Tape & Reel format can be used with appropriate handling procedures.

Frequently Asked Questions (FAQ)

Q: Are the SN74ALVC04RGYRG4 and SN74ALVC04RGYR electrically identical?

A: Yes. Both parts are manufactured by Texas Instruments with identical electrical specifications, logic function, operating temperature range, and supply voltage requirements. All timing parameters, input/output logic levels, and current ratings are equivalent.

Q: What is the difference between these two part numbers?

A: The primary difference is packaging format. The SN74ALVC04RGYRG4 uses individual packaging, while the SN74ALVC04RGYR is supplied in Tape & Reel (TR) format. The die and electrical performance are identical.

Q: Can I use the Tape & Reel version in place of the individual package version?

A: Yes. The Tape & Reel format contains the same component and is suitable for direct substitution. Tape & Reel packaging is standard for automated assembly processes. If manual assembly or prototype work is required, the component can be removed from the tape and used identically to the individual package version.

Q: Why is the main part number discontinued while the substitute is active?

A: Product status reflects supplier inventory and distribution decisions. The SN74ALVC04RGYR in Tape & Reel format remains in active production and distribution, making it the recommended source for ongoing component procurement.

Q: Are compliance certifications identical between these parts?

A: Yes. Both parts carry ROHS3 compliance, identical Moisture Sensitivity Level (MSL 2, 1 Year), and are manufactured to the same quality standards by Texas Instruments.

Q: What is the 14-VQFN package specification?

A: The 14-VQFN is a Very Thin Quad Flat No-Lead package with dimensions of 4.6mm x 4.6mm. This surface mount package includes an exposed pad for thermal management and is standard for low-voltage logic ICs in this family.
