SN74LVC2G08DCURE4 Equivalent & Substitute Parts

Part Overview

The SN74LVC2G08DCURE4 is a dual 2-input AND gate logic IC manufactured by Texas Instruments in 8-VSSOP surface mount packaging. This component is discontinued at DiGi Electronics, making equivalent substitute parts necessary for ongoing design support and procurement. The 74LVC2G08 series provides low-voltage CMOS logic functionality suitable for applications requiring AND gate operations across a 1.65V to 5.5V supply range.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SN74LVC2G08DCURE4 is determined by the following criteria:

Parametric Equivalents maintain identical electrical specifications across all critical parameters: logic type, circuit count, input count, supply voltage range, output current ratings, propagation delay, operating temperature range, and RoHS/MSL compliance. These parts differ only in packaging format (Cut Tape vs. Digi-Reel) or manufacturer, with no functional impact on circuit performance.

Upgrade Substitutes (Nexperia 74LVC2G08DC,125 and 74LVC2G08DP,125) provide enhanced specifications in quiescent current (4 µA vs. 10 µA) and input logic level thresholds, while maintaining all other critical parameters. The 74LVC2G08DP,125 variant uses 8-TSSOP packaging instead of 8-VSSOP, requiring PCB layout verification for pin compatibility.

Manufacturer Recommended Substitute (74LVC2G08DC-Q100H) is qualified to AEC-Q100 automotive standards and includes the same electrical upgrades as standard Nexperia variants, suitable for applications requiring automotive-grade components.

Parameter Comparison

Engineering Selection Recommendations

For direct replacement with identical specifications: Select SN74LVC2G08DCUR or SN74LVC2G08DCUT. Both are Texas Instruments products with active product status and maintain all electrical and thermal parameters of the discontinued SN74LVC2G08DCURE4. These parts differ only in packaging format (Cut Tape & Digi-Reel) and inventory availability.

For improved power efficiency: Select 74LVC2G08DC,125 or 74LVC2G08DP,125 from Nexperia USA Inc. These variants reduce quiescent current from 10 µA to 4 µA, providing lower standby power consumption while maintaining identical propagation delay and output current specifications. Both are active products with ROHS3 compliance.

For automotive applications: Select 74LVC2G08DC-Q100H, which combines the power efficiency improvements of the Nexperia variants with AEC-Q100 automotive qualification. This part is suitable for automotive-grade designs requiring enhanced reliability documentation.

For package-constrained designs: The 74LVC2G08DP,125 uses 8-TSSOP packaging (0.118", 3.00mm Width) instead of 8-VFSOP (0.091", 2.30mm Width). PCB layout and footprint verification is required before selection, as pin pitch and body dimensions differ.

Frequently Asked Questions (FAQ)

Q: Can I use SN74LVC2G08DCUR as a direct replacement for SN74LVC2G08DCURE4?

A: Yes. SN74LVC2G08DCUR is a parametric equivalent with identical electrical specifications, operating temperature range, and package dimensions. The only difference is packaging format (Cut Tape & Digi-Reel vs. the original format). No circuit modifications are required.

Q: What is the difference between Texas Instruments and Nexperia variants?

A: Both manufacturers produce 74LVC2G08 logic gates meeting the same functional specifications. Nexperia variants (74LVC2G08DC,125 and 74LVC2G08DP,125) offer reduced quiescent current (4 µA vs. 10 µA). Texas Instruments variants maintain the original 10 µA specification. All variants are ROHS3 compliant and MSL 1.

Q: Can I substitute 74LVC2G08DP,125 for the original part?

A: Electrical substitution is valid, but package substitution requires verification. The 74LVC2G08DP,125 uses 8-TSSOP packaging (0.118", 3.00mm Width) versus the original 8-VFSOP (0.091", 2.30mm Width). Footprint, pin pitch, and PCB layout compatibility must be confirmed before use.

Q: Is 74LVC2G08DC-Q100H suitable for non-automotive applications?

A: Yes. The AEC-Q100 automotive qualification is an additional certification that does not restrict use in non-automotive designs. This part provides the same electrical performance and power efficiency as standard Nexperia variants with enhanced reliability documentation.

Q: What parameters determine substitution compatibility?

A: The critical parameters are logic type (AND Gate), circuit count (2), input count (2), supply voltage range (1.65V ~ 5.5V), output current (32mA), propagation delay (3.8ns @ 5V, 50pF), operating temperature (-40°C ~ 125°C), and package footprint. All listed substitutes maintain these specifications except 74LVC2G08DP,125, which uses different packaging.
