Key Parameters

Substitute Part Grouping Explanation

Substitution for the SN74LVC2G00DCURE4 is determined by the following critical parameters:

• Logic Type: NAND Gate (2 channels, 2 inputs per channel)
• Supply Voltage Range: 1.65V ~ 5.5V
• Output Current Capability: 32mA high and low
• Propagation Delay: 3.3ns @ 5V, 50pF
• Operating Temperature Range: -40°C ~ 125°C
• Surface Mount Configuration
• RoHS3 Compliance and MSL Level 1

Substitute parts are grouped into three categories:

Parametric Equivalents (Texas Instruments): SN74LVC2G00DCUR and SN74LVC2G00DCUT share identical electrical specifications and differ only in packaging format (Cut Tape vs. Tape & Reel).

Direct Manufacturer Equivalent (onsemi): NL27WZ00USG provides equivalent NAND gate functionality with identical supply voltage, output current, and propagation delay specifications, though in a different package designation (US8 vs. VSSOP).

Manufacturer Recommended Equivalents (Nexperia): 74LVC2G00DP,125, 74LVC2G00DC,125, and 74LVC2G00DC-Q100H maintain the same logic function and electrical performance within the 74LVC2G00 base product family, with variations in package type (TSSOP vs. VSSOP) and automotive qualification.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Package): SN74LVC2G00DCUR and SN74LVC2G00DCUT are the primary substitutes, offering identical electrical specifications and the same 8-VSSOP package footprint. Both parts are active and in stock, with SN74LVC2G00DCUR available in higher quantities (95,300 pcs). These parts require no PCB layout modifications.

For Cross-Manufacturer Substitution: NL27WZ00USG from onsemi provides equivalent NAND gate functionality with identical supply voltage and output current ratings. The propagation delay is 3.6ns (0.3ns slower than the original), which remains within typical logic gate performance margins. The US8 package maintains the same 8-VFSOP physical dimensions. This part is active with 65,200 pcs in stock.

For Package Variant Substitution: The Nexperia 74LVC2G00 family (74LVC2G00DP,125, 74LVC2G00DC,125, and 74LVC2G00DC-Q100H) maintains identical electrical performance. The 74LVC2G00DP,125 uses an 8-TSSOP package with slightly larger dimensions (0.118" vs. 0.091" width), requiring PCB layout verification. The 74LVC2G00DC,125 maintains the 8-VSSOP package. The 74LVC2G00DC-Q100H includes AEC-Q100 automotive qualification for applications requiring automotive-grade components.

For Automotive Applications: 74LVC2G00DC-Q100H is the qualified choice, providing AEC-Q100 certification with identical electrical specifications and 8-VSSOP packaging.

Frequently Asked Questions (FAQ)

Q: Can SN74LVC2G00DCUR be used as a direct replacement for SN74LVC2G00DCURE4?

A: Yes. Both parts share identical electrical specifications, supply voltage range (1.65V ~ 5.5V), output current (32mA), propagation delay (3.3ns @ 5V, 50pF), and operating temperature range (-40°C ~ 125°C). The only difference is packaging format (Cut Tape vs. Digi-Reel). No circuit modifications are required.

Q: What is the difference between the 8-VSSOP and 8-TSSOP packages?

A: Both are 8-pin surface mount packages with identical pin configurations. The 8-VSSOP has a width of 0.091" (2.30mm), while the 8-TSSOP has a width of 0.118" (3.00mm). PCB footprints differ; verify your design layout before substituting 74LVC2G00DP,125 (TSSOP) for the original VSSOP package.

Q: Is NL27WZ00USG compatible with the original part?

A: Yes, with minor timing consideration. The NL27WZ00USG provides equivalent NAND gate functionality with identical supply voltage and output current. The propagation delay is 3.6ns (0.3ns slower than 3.3ns). For most digital logic applications, this difference is negligible. The part is active and widely available.

Q: Which substitute has the widest operating temperature range?

A: NL27WZ00USG operates from -55°C ~ 125°C, providing a 15°C lower minimum temperature compared to the original part (-40°C ~ 125°C). All other substitutes maintain the -40°C ~ 125°C range.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant with MSL Level 1 (Unlimited moisture sensitivity), matching the original part's environmental certifications.

Q: What is the inventory status of each substitute?

A: SN74LVC2G00DCUR has the highest availability (95,300 pcs), followed by NL27WZ00USG (65,200 pcs), 74LVC2G00DC,125 (7,902 pcs), 74LVC2G00DC-Q100H (3,148 pcs), and 74LVC2G00DP,125 (2,100 pcs). All are listed as active products.
