74LVC00ADR2G Equivalent & Substitute Parts

Part Overview

The 74LVC00ADR2G is a NAND Gate IC featuring 4 channels with 2 inputs per channel in a 14-SOIC surface mount package, manufactured by onsemi. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and procurement continuity. The 74LVC series logic gate serves as a fundamental building block in digital circuit design, and equivalent alternatives must maintain functional compatibility while meeting current supply chain requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74LVC00ADR2G is determined by the following critical parameters:

Functional Equivalence: Logic type (NAND Gate), number of circuits (4), and number of inputs (2) must remain identical across all substitute parts.

Package Compatibility: The 14-SOIC surface mount package is mandatory for direct board-level substitution without layout modifications.

Electrical Operating Range: Supply voltage range, quiescent current, output current ratings, input logic levels, and propagation delay characteristics must fall within acceptable tolerances for the target application.

Environmental & Compliance Requirements: Operating temperature range, RoHS compliance status, and moisture sensitivity level must meet or exceed the original specification.

The MC74LCX00DR2G qualifies as a substitute based on matching logic function, package type, and compliance certifications, despite differences in supply voltage range and operating temperature limits.

Parameter Comparison

Engineering Selection Recommendations

The MC74LCX00DR2G is an active product substitute for the obsolete 74LVC00ADR2G. Both components are manufactured by onsemi, share identical logic function and package specifications, and maintain ROHS3 compliance with unlimited moisture sensitivity ratings.

The MC74LCX00DR2G exhibits lower quiescent current consumption (10 µA versus 40 µA), which may provide power efficiency benefits in battery-powered or low-power applications. However, the substitute part specifies a narrower supply voltage range (2V ~ 3.6V versus 1.2V ~ 3.6V) and reduced maximum operating temperature (85°C versus 125°C). Design verification is necessary to confirm that these parameter differences are acceptable for the specific application context.

Frequently Asked Questions (FAQ)

Q: Can the MC74LCX00DR2G be used as a direct replacement for the 74LVC00ADR2G?

A: Both parts share identical logic function (4-channel NAND gate), pin count, and 14-SOIC package configuration. Substitution is feasible provided the application operates within the MC74LCX00DR2G supply voltage range (2V ~ 3.6V minimum) and temperature range (-40°C ~ 85°C maximum).

Q: What are the key differences between these two parts?

A: The primary differences are product status (obsolete versus active), supply voltage range (1.2V ~ 3.6V versus 2V ~ 3.6V), quiescent current (40 µA versus 10 µA), and maximum operating temperature (125°C versus 85°C). Propagation delay and output current characteristics are equivalent.

Q: Are there any package or mounting considerations for substitution?

A: Both parts use identical 14-SOIC surface mount packaging with 0.154" width and 3.90mm dimensions. No PCB layout or footprint modifications are required for substitution.

Q: What compliance certifications apply to both parts?

A: Both the 74LVC00ADR2G and MC74LCX00DR2G are ROHS3 compliant, REACH unaffected, and classified as MSL 1 (unlimited moisture sensitivity). Both carry EAR99 export classification.

Q: Which part should be selected for new designs?

A: The MC74LCX00DR2G is the recommended choice for new designs due to its active product status, lower quiescent current consumption, and continued manufacturer support. The 74LVC00ADR2G should be reserved for legacy system maintenance only.
