SN74LVC02ADRG4 Equivalent & Substitute Parts

Part Overview

The SN74LVC02ADRG4 is a NOR Gate IC featuring 4 channels with 2 inputs per channel in a 14-SOIC surface mount package, manufactured by Texas Instruments. This part is discontinued at DiGi Electronics, necessitating identification of equivalent and substitute components for ongoing design requirements and production needs. The device operates across a 1.65V to 3.6V supply voltage range with low quiescent current and fast propagation delay characteristics suitable for low-power logic applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN74LVC02ADRG4 is determined by the following critical parameters: logic type (NOR Gate), circuit count (4 channels), input count (2 per channel), package type (14-SOIC), and electrical specifications including supply voltage range, propagation delay, and output current capability.

Substitute parts are grouped into two categories:

Parametric Equivalents maintain identical electrical specifications and package configuration, differing only in packaging format (Tape & Reel vs. tube) or product status. These parts are direct functional replacements.

Manufacturer Recommended Substitutes may exhibit variations in specific electrical parameters such as supply voltage range, quiescent current, or propagation delay, but maintain the same logic function, circuit count, input configuration, and package footprint. These parts require engineering evaluation based on application-specific requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: SN74LVC02ADR

The SN74LVC02ADR is the recommended primary substitute. Manufactured by Texas Instruments, it maintains identical electrical specifications to the SN74LVC02ADRG4 across all critical parameters including supply voltage range (1.65V ~ 3.6V), quiescent current (1 µA), propagation delay (4.2ns @ 3.3V, 50pF), and operating temperature range (-40°C ~ 125°C). The part differs only in packaging format (Tape & Reel vs. tube) and carries Active product status with 22,570 units in stock. ROHS3 compliance and MSL 1 rating are maintained.

Secondary Substitute: SN74LVC02ADT

The SN74LVC02ADT provides identical electrical performance to the SN74LVC02ADRG4 with the same supply voltage, quiescent current, propagation delay, and operating temperature specifications. This part is discontinued at DiGi Electronics with 1,114 units available. Use this option only when SN74LVC02ADR is unavailable and existing inventory is acceptable.

Alternative Substitutes: MC74LCX02DR2G and MC74LCX02DG

The onsemi MC74LCX02DR2G and MC74LCX02DG are manufacturer-recommended substitutes with functional equivalence but parameter variations. Both operate at 2V ~ 3.6V supply voltage (vs. 1.65V ~ 3.6V for the original), exhibit higher quiescent current (10 µA vs. 1 µA), and demonstrate slower propagation delay (5.5ns vs. 4.2ns @ 3.3V, 50pF). Operating temperature range is limited to -40°C ~ 85°C. The MC74LCX02DR2G is Active with 2,700 units in stock; MC74LCX02DG is Obsolete with 1,682 units available. These substitutes are suitable only for applications where the reduced supply voltage range, higher quiescent current, and slower propagation delay do not impact system performance.

NXP Alternative: 74LVC02AD,118

The NXP Semiconductors 74LVC02AD,118 is a manufacturer-recommended substitute with Active product status and 151,347 units in stock. Detailed electrical specifications are not provided in the available data. This part should be evaluated against application requirements before selection.

Frequently Asked Questions (FAQ)

Q: Can SN74LVC02ADR directly replace SN74LVC02ADRG4 in production?

A: Yes. The SN74LVC02ADR is a parametric equivalent with identical electrical specifications and 14-SOIC package footprint. The only difference is packaging format (Tape & Reel vs. tube). No circuit redesign is required.

Q: What are the key differences between the Texas Instruments 74LVC02 variants and the onsemi MC74LCX02 alternatives?

A: The Texas Instruments SN74LVC02 series operates at 1.65V ~ 3.6V supply voltage with 1 µA quiescent current and 4.2ns propagation delay. The onsemi MC74LCX02 series operates at 2V ~ 3.6V with 10 µA quiescent current and 5.5ns propagation delay. The onsemi variants also have a reduced operating temperature range (-40°C ~ 85°C vs. -40°C ~ 125°C). These differences may impact low-power or high-temperature applications.

Q: Is the 14-SOIC package footprint identical across all substitute parts?

A: Yes. All substitute parts listed use the 14-SOIC (0.154", 3.90mm Width) package. PCB layout and footprint remain unchanged.

Q: What is the inventory status of recommended substitutes?

A: SN74LVC02ADR (Active, 22,570 units), SN74LVC02ADT (Discontinued, 1,114 units), MC74LCX02DR2G (Active, 2,700 units), MC74LCX02DG (Obsolete, 1,682 units), and 74LVC02AD,118 (Active, 151,347 units).

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitutes maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the original SN74LVC02ADRG4 specifications.

Q: Which substitute should be selected for new designs?

A: For new designs, select SN74LVC02ADR (Texas Instruments, Active status, parametric equivalent). For applications with relaxed performance requirements, MC74LCX02DR2G (onsemi, Active status) is an alternative. Avoid obsolete parts (MC74LCX02DG) and discontinued parts (SN74LVC02ADT) for new production.
