74LVC00APW,112 NAND Gate IC Equivalent & Substitute Parts

Part Overview

The 74LVC00APW,112 is a 4-channel 2-input NAND gate logic IC manufactured by Nexperia USA Inc. in 14-TSSOP surface mount packaging. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The 74LVC00 series provides standard logic gating functionality with low-voltage CMOS technology suitable for digital logic applications requiring 1.2V to 3.6V supply operation.

Substitute Part Grouping Explanation

Substitution for the 74LVC00APW,112 is determined by the following critical parameters:

Functional Requirements: Logic type (NAND gate), circuit count (4 channels), and input configuration (2-input) must remain identical across all substitutes.

Electrical Compatibility: Supply voltage range, output current capability, and propagation delay characteristics must support the original application requirements.

Physical Compatibility: All substitutes must use the 14-TSSOP package format to ensure PCB footprint compatibility without redesign.

Compliance & Status: Active product status is preferred for long-term availability, though discontinued parts may serve as interim solutions. All substitutes maintain ROHS3 compliance and identical moisture sensitivity levels.

The substitute parts are grouped into two technology families: the 74LVC series (Nexperia/Texas Instruments) and the 74LCX series (onsemi/STMicroelectronics). Both families provide functionally equivalent 4-channel 2-input NAND gates in identical packaging with compatible electrical characteristics.

Engineering Selection Recommendations

Primary Substitutes (74LVC Series - Texas Instruments):

The SN74LVC00APWR, SN74LVC00APW, and SN74LVC00APWT are direct functional equivalents with active product status. These parts maintain the same logic family (74LVC), identical package format, and superior electrical characteristics including lower quiescent current (1 µA vs. 40 µA) and faster propagation delay (4.1ns vs. 4.3ns). The extended operating temperature range (-40°C to 125°C) matches the original specification. These are the recommended first choice for replacement.

Secondary Substitutes (74LCX Series - onsemi/STMicroelectronics):

The 74LCX00 variants (74LCX00MTCX, 74LCX00YTTR, MC74LCX00DTG, MC74LCX00DTR2G) provide functional equivalence with active status but operate within a narrower supply voltage range (2V ~ 3.6V minimum vs. 1.2V). These parts are suitable for applications where the minimum supply voltage requirement of 2V is acceptable. The 74LCX00YTTR includes AEC-Q100 automotive qualification for applications requiring automotive-grade components.

Interim Solutions:

SN74LVC00AMPWREP and SN74LVC00APWE4 remain available but are discontinued at DiGi Electronics. These may serve as interim solutions where existing inventory exists but should not be selected for new designs requiring long-term availability.

Packaging Considerations:

All substitutes are available in 14-TSSOP surface mount packaging. Verify the specific packaging variant (Cut Tape, Tape & Reel, or Tube) matches procurement and assembly requirements for your application.

Frequently Asked Questions (FAQ)

Q: Can I use a 74LCX00 part as a direct replacement for the 74LVC00APW,112?

A: Yes, functionally. Both are 4-channel 2-input NAND gates in 14-TSSOP packaging with identical logic operation and output current ratings. However, the 74LCX series has a minimum supply voltage of 2V, while the original 74LVC00 operates from 1.2V. If your application requires operation below 2V, use the 74LVC series instead.

Q: What is the difference between the Texas Instruments 74LVC variants (APWR, APW, APWT)?

A: These are the same part in different packaging formats. APWR is Cut Tape & Digi-Reel, APW is Tube, and APWT is Tape & Reel. The electrical specifications and functionality are identical. Select based on your procurement and assembly process requirements.

Q: Why does the original 74LVC00APW,112 show higher quiescent current (40 µA) than the Texas Instruments substitutes (1 µA)?

A: This reflects manufacturing process improvements and technology evolution within the 74LVC family. The Texas Instruments versions use more efficient CMOS processes. Both meet the functional requirements for NAND gate operation, but the newer parts offer superior power efficiency.

Q: Is the 74LCX00YTTR suitable for automotive applications?

A: Yes. The 74LCX00YTTR carries AEC-Q100 automotive qualification and is the only substitute in this list with explicit automotive-grade certification. Use this part for automotive or safety-critical applications requiring qualified components.

Q: What is the propagation delay difference between substitutes, and does it matter?

A: Propagation delays range from 4.1ns to 5.5ns at 3.3V with 50pF load. For most digital logic applications, this 1.4ns variation is negligible. Select based on timing-critical requirements only if your circuit operates at frequencies where sub-nanosecond delays impact system performance.

Q: Can I mix different substitute parts in the same design?

A: Yes, provided all parts meet your application's voltage supply range and operating temperature requirements. However, for consistency and simplified procurement, standardize on a single substitute part number across your design.
