74LVC2G126DCTRG4 Equivalent & Substitute Parts

Part Overview

The 74LVC2G126DCTRG4 is a non-inverting buffer logic IC manufactured by Texas Instruments, featuring 2 elements with 1 bit per element and 3-state output capability. This device is designed for low-voltage CMOS applications with supply voltage range from 1.65V to 5.5V and operates across the industrial temperature range of -40°C to 125°C. The part is currently discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74LVC2G126DCTRG4 is determined by strict equivalence across the following critical parameters:

• Logic Type: Buffer, Non-Inverting
• Number of Elements: 2
• Number of Bits per Element: 1
• Output Type: 3-State
• Current - Output High, Low: 32mA, 32mA
• Voltage - Supply: 1.65V ~ 5.5V
• Operating Temperature: -40°C ~ 125°C (TA)
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Substitute parts are grouped into two categories: Texas Instruments parametric equivalents with alternative packaging configurations, and manufacturer-recommended alternatives from Nexperia USA Inc. with different package types. All listed substitutes maintain identical electrical specifications and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring direct pin-compatible replacement with identical package dimensions, select SN74LVC2G126DCTR. This part maintains the same 8-LSSOP/8-MSOP package footprint as the original 74LVC2G126DCTRG4 and carries Active product status with substantial inventory availability.

For applications where package type flexibility is acceptable, SN74LVC2G125DCTR provides the highest inventory level (35,200 pcs) with Active status and identical electrical specifications. The 74LVC2G125 base product number indicates functionally equivalent buffer operation within the same 74LVC series.

For applications where alternative package geometries are acceptable, the Nexperia USA Inc. 74LVC2G126DP,125 offers the largest inventory (113,821 pcs) with Active product status. This part uses an 8-TSSOP package with different physical dimensions but maintains all electrical and compliance specifications.

All recommended substitutes maintain ROHS3 compliance, MSL Level 1 rating, and identical electrical performance across the specified voltage and temperature ranges.

Frequently Asked Questions (FAQ)

Q: Can I use 74LVC2G125 variants as direct replacements for 74LVC2G126DCTRG4?

A: Yes. The 74LVC2G125 and 74LVC2G126 base products are functionally equivalent within the 74LVC series, sharing identical electrical specifications for buffer operation, output current ratings, supply voltage range, and operating temperature. All listed 74LVC2G125 variants meet the substitution criteria.

Q: What is the difference between the packaging types listed (Tape & Reel vs. Cut Tape & Digi-Reel)?

A: Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® represent different supply formats for surface mount components. Both formats contain identical parts; the difference is in the delivery method. Tape & Reel provides continuous reel packaging, while Cut Tape & Digi-Reel® provides pre-cut tape segments. Component electrical and mechanical specifications remain unchanged.

Q: Are the Nexperia parts (74LVC2G126DC,125 and 74LVC2G126DP,125) compatible with the original Texas Instruments part?

A: Yes, from an electrical standpoint. Both manufacturers' parts meet identical specifications for logic type, output configuration, current ratings, voltage supply, and operating temperature. However, the Nexperia parts use different package types (8-VFSOP and 8-TSSOP respectively) compared to the original 8-LSSOP/8-MSOP package. PCB layout modifications are required for physical compatibility.

Q: Why is the original 74LVC2G126DCTRG4 discontinued while substitutes remain in Active status?

A: Product discontinuation at distributor level does not indicate functional obsolescence. Substitute parts in Active status from the same or alternative manufacturers provide equivalent functionality and are recommended for new designs and ongoing production.

Q: What does MSL Level 1 (Unlimited) mean for component handling?

A: Moisture Sensitivity Level 1 indicates the component has unlimited shelf life without special moisture control measures. No baking or desiccant storage is required prior to assembly, simplifying inventory management and component handling procedures.
