74LVC2G38DC,125 Equivalent & Substitute Parts

Part Overview

The 74LVC2G38DC,125 is a NAND Gate IC featuring 2 channels with 2 inputs per channel and open drain output configuration in an 8-VSSOP package. Manufactured by Nexperia USA Inc., this logic component operates across a wide supply voltage range of 1.65V to 5.5V and is classified as Active product status. Substitute parts are necessary when the original manufacturer part becomes unavailable, when alternative packaging formats are required for assembly compatibility, or when sourcing from different manufacturers is preferred for supply chain optimization.

Substitute Part Grouping Explanation

Substitution of the 74LVC2G38DC,125 is determined by strict equivalence across the following critical parameters: logic type (NAND Gate), circuit count (2 channels), input count (2 inputs per channel), open drain feature, supply voltage range (1.65V ~ 5.5V), output current capability (32mA), input logic levels, and surface mount configuration. All substitute parts listed maintain these core electrical specifications. Packaging format variations (Tape & Reel versus Cut Tape) and minor differences in quiescent current and propagation delay do not affect functional interchangeability within the specified electrical operating envelope.

Engineering Selection Recommendations

All listed substitute parts maintain functional equivalence with the 74LVC2G38DC,125 across core electrical parameters including logic operation, supply voltage range, output current capability, and input logic thresholds. All parts are Active status products with ROHS3 compliance and MSL 1 rating, ensuring consistent availability and environmental compliance.

The Texas Instruments SN74LVC2G38DCUR and SN74LVC2G38DCUT variants offer identical package geometry (8-VFSOP) to the original Nexperia part, providing direct mechanical compatibility for PCB assembly. The SN74LVC2G38DCTR variant uses an alternative package format (SM8 / 8-LSSOP, 8-MSOP) with different physical dimensions and requires PCB layout adjustment.

Operating temperature range differs between manufacturers: the Nexperia part supports -40°C to 125°C, while Texas Instruments variants support -40°C to 85°C. Quiescent current specifications show the Nexperia part at 4 µA maximum versus 10 µA for Texas Instruments parts. Propagation delay at 5V and 50pF load is 3.3ns for Nexperia versus 3.9ns for Texas Instruments variants. These differences remain within acceptable tolerances for standard logic circuit applications.

Frequently Asked Questions (FAQ)

Q: Can SN74LVC2G38DCTR be used as a direct replacement for 74LVC2G38DC,125?

A: SN74LVC2G38DCTR is electrically equivalent but uses a different package format (SM8 / 8-LSSOP, 8-MSOP with 0.110" width) compared to the original 8-VFSOP (0.091" width). Direct PCB substitution requires layout modification. For mechanical compatibility without redesign, use SN74LVC2G38DCUR or SN74LVC2G38DCUT instead.

Q: What are the key differences between the three Texas Instruments substitutes?

A: SN74LVC2G38DCUR and SN74LVC2G38DCUT are mechanically and electrically identical, differing only in packaging format (Tape & Reel). SN74LVC2G38DCTR differs in both package geometry and supplier device package designation (SM8 versus 8-VSSOP), requiring PCB layout changes for implementation.

Q: Are there temperature range limitations when substituting with Texas Instruments parts?

A: Texas Instruments variants operate to 85°C maximum, compared to 125°C for the Nexperia original. Applications requiring operation above 85°C must use the original 74LVC2G38DC,125 or verify that system thermal design maintains component temperature within the 85°C limit.

Q: Do all substitute parts meet the same compliance standards?

A: All parts listed are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. Compliance certifications are equivalent across all variants.

Q: What is the significance of the quiescent current difference?

A: The Nexperia part specifies 4 µA maximum quiescent current versus 10 µA for Texas Instruments parts. For battery-powered or ultra-low-power applications where standby current is critical, the Nexperia part offers superior performance. For standard applications, this difference is typically negligible.
