74LVC00AD,112 NAND Gate IC Equivalent & Substitute Parts

Part Overview

The 74LVC00AD,112 is a 4-channel 2-input NAND gate logic IC manufactured by Nexperia USA Inc. in 14-SOIC surface mount packaging. This part is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production support. The 74LVC series operates across a wide voltage range (1.2V to 3.6V) with low quiescent current and fast propagation delay characteristics suitable for general-purpose logic applications.

Substitute Part Grouping Explanation

Substitution of the 74LVC00AD,112 is determined by the following critical parameters:

Logic Function: All substitutes must be 4-channel 2-input NAND gates
Package Type: All substitutes must use 14-SOIC (0.154", 3.90mm Width) surface mount packaging
Output Current Capability: Minimum 24mA output drive for both high and low states
Operating Temperature: Must support -40°C to 125°C range or equivalent
Voltage Supply Compatibility: Must operate within overlapping voltage ranges with the main part
Propagation Delay: Must meet or exceed speed performance at 3.3V, 50pF load

Substitute parts are grouped into two categories based on voltage supply range compatibility and quiescent current characteristics:

Category A (74LVC Series - Texas Instruments): SN74LVC00AD, SN74LVC00ADR, SN74LVC00ADT, SN74LVC00ADRG4, SN74LVC00AQDREP. These parts maintain the full 1.65V ~ 3.6V voltage range with ultra-low quiescent current (1µA maximum).

Category B (74LCX Series - Fairchild Semiconductor & onsemi): 74LCX00MX, MC74LCX00DG, MC74LCX00DR2G. These parts operate at 2V ~ 3.6V with 10µA quiescent current and represent active production alternatives.

Engineering Selection Recommendations

Primary Substitutes (Recommended for New Designs)

The SN74LVC00AD, SN74LVC00ADR, and SN74LVC00ADT from Texas Instruments are the preferred substitutes. These parts maintain active product status, offer superior quiescent current performance (1µA vs. 40µA), faster propagation delay (4.1ns vs. 4.3ns), and support the full extended temperature range (-40°C to 125°C). All three variants are ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Secondary Substitutes (Voltage-Limited Applications)

The SN74LVC00AQDREP, MC74LCX00DG, MC74LCX00DR2G, and 74LCX00MX are suitable for applications where the minimum supply voltage requirement is 2V or higher. These parts are active production items with ROHS3 compliance. The onsemi and Fairchild variants operate at reduced maximum temperature (-40°C to 85°C), which may limit use in extended temperature applications.

Avoid

The SN74LVC00ADRG4 is discontinued at DiGi Electronics and should not be selected for new designs despite active status at other distributors.

Frequently Asked Questions (FAQ)

Q: Can I substitute the 74LVC00AD,112 with any of the listed parts?

A: Direct substitution is possible only if your application meets the voltage and temperature requirements of the substitute. All listed parts share identical logic function, pin count, and 14-SOIC packaging. Verify that your circuit's minimum supply voltage and maximum operating temperature do not exceed the substitute part's specifications.

Q: What is the difference between the Texas Instruments 74LVC and Fairchild/onsemi 74LCX variants?

A: The 74LVC series (Texas Instruments) operates at 1.65V minimum supply voltage with 1µA quiescent current. The 74LCX series (Fairchild/onsemi) requires 2V minimum supply voltage with 10µA quiescent current. Both families deliver identical output current (24mA) and package in 14-SOIC. The 74LVC series is preferred for low-voltage and low-power applications.

Q: Does packaging type (Tube, Tape & Reel, Bulk) affect electrical performance?

A: No. Packaging type affects only handling, storage, and assembly processes. Electrical specifications remain identical across all packaging variants of the same part number base.

Q: Why is the operating temperature range important for substitution?

A: The original 74LVC00AD,112 supports -40°C to 125°C. Substitutes with -40°C to 85°C maximum temperature cannot be used in applications requiring operation above 85°C. Verify your application's temperature requirements before selecting a substitute.

Q: Are all listed substitutes RoHS3 compliant?

A: Yes. All substitute parts listed carry ROHS3 compliance certification, matching the original part's environmental compliance status.
