Substitute Part Grouping Explanation

Substitution eligibility for the SN74LVC2G38DCUTE4 is determined by strict parametric equivalence across the following critical parameters:

Logic configuration (NAND Gate, 2 channels, 2 inputs per channel), open drain output feature, supply voltage range (1.65V ~ 5.5V), input logic levels (Low: 0.7V ~ 0.8V, High: 1.7V ~ 2V), output current capability (32mA maximum), propagation delay performance (3.9ns @ 5V, 50pF), operating temperature range (-40°C ~ 85°C), and physical package format (8-VFSOP).

Substitute parts are categorized as follows:

Parametric Equivalents maintain identical electrical specifications and packaging. These parts are direct functional replacements with no performance trade-offs.

Upgrade parts offer enhanced specifications (lower quiescent current, faster propagation delay, or extended temperature range) while maintaining core functional compatibility and the same physical package.

Manufacturer Recommended parts are designated by the original manufacturer as approved alternatives within the same product family.

Parameter Comparison

Engineering Selection Recommendations

For applications currently using the obsolete SN74LVC2G38DCUTE4, the following selection criteria apply:

SN74LVC2G38DCUR and SN74LVC2G38DCUT are parametric equivalents manufactured by Texas Instruments with active product status. Both maintain identical electrical specifications and 8-VFSOP packaging. Selection between these two depends on packaging requirements: SN74LVC2G38DCUR and SN74LVC2G38DCUT are supplied in Tape & Reel format for automated assembly processes.

74LVC2G38DC,125 manufactured by NXP USA Inc. is classified as an upgrade substitute. It provides enhanced performance through reduced quiescent current (4 µA versus 10 µA) and faster propagation delay (3.3ns versus 3.9ns at 5V, 50pF). Additionally, it supports an extended operating temperature range of -40°C to 125°C compared to the original -40°C to 85°C specification. This part is supplied in bulk packaging and maintains ROHS3 compliance.

74LVC2G38DP,125 is designated as the manufacturer-recommended alternative by NXP Semiconductors. Detailed electrical specifications for this part are not fully provided in the available data.

All substitute parts maintain the critical functional parameters: 2-channel NAND gate configuration with 2 inputs per channel, open drain output, 1.65V to 5.5V supply voltage range, 32mA output current capability, and identical input logic level thresholds. Physical package compatibility is confirmed across all recommended substitutes in the 8-VFSOP format.

Frequently Asked Questions (FAQ)

Q: Can SN74LVC2G38DCUR or SN74LVC2G38DCUT be used as direct replacements for the obsolete SN74LVC2G38DCUTE4?

A: Yes. Both parts are parametric equivalents with identical electrical specifications and package format. The primary difference is packaging type: SN74LVC2G38DCUR and SN74LVC2G38DCUT are supplied in Tape & Reel format suitable for automated assembly, whereas the original part was supplied in tube packaging.

Q: What are the advantages of using 74LVC2G38DC,125 from NXP as a substitute?

A: The 74LVC2G38DC,125 offers two performance improvements: reduced quiescent current consumption (4 µA versus 10 µA) and faster propagation delay (3.3ns versus 3.9ns at 5V with 50pF load). It also supports an extended operating temperature range to 125°C. These enhancements make it suitable for applications requiring lower power consumption or higher temperature operation while maintaining full functional compatibility.

Q: Are all substitute parts ROHS3 compliant?

A: The Texas Instruments parametric equivalents (SN74LVC2G38DCUR and SN74LVC2G38DCUT) are confirmed ROHS3 compliant. RoHS compliance status for the NXP parts is not specified in the available data.

Q: Do all substitute parts use the same 8-VFSOP package?

A: Yes. All recommended substitute parts use the 8-VFSOP (0.091", 2.30mm Width) package format, ensuring physical and mechanical compatibility with the original SN74LVC2G38DCUTE4 in PCB layouts and socket configurations.

Q: What is the difference between the Texas Instruments and NXP substitute options?

A: Texas Instruments parametric equivalents (SN74LVC2G38DCUR and SN74LVC2G38DCUT) maintain identical specifications to the original part. The NXP 74LVC2G38DC,125 provides enhanced performance with lower quiescent current and faster propagation delay, plus extended temperature range. Selection depends on whether the application requires exact specification matching or can benefit from improved performance characteristics.

Q: Can the 74LVC2G38DP,125 be used as a substitute?

A: The 74LVC2G38DP,125 is designated as a manufacturer-recommended alternative by NXP Semiconductors. However, complete electrical specifications for this part are not provided in the available technical data, limiting detailed compatibility assessment.
