SN74ALVC04NSR Equivalent & Substitute Parts

Part Overview

The SN74ALVC04NSR is a 6-channel inverter logic IC manufactured by Texas Instruments in a 14-SO surface mount package. This device is classified as obsolete, making equivalent substitute parts necessary for ongoing production and maintenance applications. The 74ALVC04 series provides standard inverter functionality across the low-voltage CMOS logic family, operating from 1.65V to 3.6V supply voltage with propagation delays suitable for general-purpose digital logic applications.

Substitute Part Grouping Explanation

Substitution of the SN74ALVC04NSR is based on the following criteria derived from the provided parameters:

Primary Substitution Criteria:

• Logic type must be Inverter
• Number of circuits must be 6
• Number of inputs must be 1
• Supply voltage range must be 1.65V ~ 3.6V
• Operating temperature range must be -40°C ~ 85°C
• Mounting type must be Surface Mount
• Package must be 14-SOIC

The 74ALVC04D,118 manufactured by Nexperia USA Inc. meets all primary substitution criteria. This part is classified as Active product status, providing long-term availability compared to the obsolete SN74ALVC04NSR.

Parameter Comparison

Engineering Selection Recommendations

The 74ALVC04D,118 from Nexperia USA Inc. is the qualified substitute for the obsolete SN74ALVC04NSR. Both parts maintain ROHS3 compliance and identical MSL ratings. The substitute part offers Active product status, ensuring continued availability and supply chain stability.

The 74ALVC04D,118 demonstrates improved propagation delay performance (2ns versus 2.8ns at 3.3V, 50pF), while quiescent current is slightly elevated (20 µA versus 10 µA). All logic levels, output drive currents, supply voltage range, and operating temperature specifications remain equivalent between the two parts.

Physical package dimensions differ between the two variants: the SN74ALVC04NSR uses a 0.209" width package, while the 74ALVC04D,118 uses a 0.154" width package. Both are 14-SOIC surface mount packages suitable for standard PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the 74ALVC04D,118 directly replace the SN74ALVC04NSR in existing designs?

A: Yes. Both parts share identical logic type, circuit count, input count, supply voltage range, operating temperature range, and output drive specifications. The 14-SOIC package footprint is compatible with standard surface mount assembly equipment, though the physical package width differs slightly.

Q: What is the difference in quiescent current between these parts?

A: The SN74ALVC04NSR specifies 10 µA maximum quiescent current, while the 74ALVC04D,118 specifies 20 µA maximum. This difference may be relevant in ultra-low-power applications where standby current is critical.

Q: Are there compliance differences between the two parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical MSL ratings of 1 (Unlimited). Both are classified under ECCN EAR99 and HTSUS 8542.39.0001.

Q: Why is the propagation delay faster in the substitute part?

A: The 74ALVC04D,118 demonstrates 2ns propagation delay at 3.3V with 50pF load, compared to 2.8ns for the SN74ALVC04NSR. This represents improved performance in the substitute part and does not create compatibility issues in designs specified for the original part.

Q: What packaging format is available for the 74ALVC04D,118?

A: The 74ALVC04D,118 is supplied in Tape & Reel (TR) format, suitable for automated assembly processes. The SN74ALVC04NSR packaging format was not specified in the provided data.
