NLSV1T34DFT2G Equivalent & Substitute Parts
Part Overview
The NLSV1T34DFT2G is a Buffer, Non-Inverting logic translator manufactured by onsemi in SC-88A (SC-70-5/SOT-353) packaging. This single-element, single-bit buffer provides push-pull output with 24mA drive capability and operates across a 0.9V to 4.5V supply range. The part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

Substitute Part Grouping Explanation
Substitution for the NLSV1T34DFT2G is determined by the following critical parameters:
Functional Equivalence: Logic type (Buffer, Non-Inverting), number of elements (1), bits per element (1), and output type (Push-Pull) must match exactly.
Electrical Compatibility: Output drive current (24mA minimum for both high and low), supply voltage range (minimum 0.9V, maximum 4.5V), and operating temperature range (-40°C to 85°C) establish the baseline electrical requirements.
Package Compatibility: The 5-TSSOP/SC-70-5/SOT-353 package defines the physical footprint. Substitutes in alternative packages (6-XSON, 6-SON, SOT-23-6) require PCB redesign and are classified as similar rather than direct equivalents.
Compliance Requirements: RoHS3 compliance and MSL 1 rating are mandatory for equivalent parts.
Substitutes are grouped into three categories:
Parametric Equivalent: NLVSV1T34DFT2G (onsemi) — identical electrical and functional specifications with automotive qualification (AEC-Q100), same package family, different packaging format (Tape & Reel vs. Cut Tape).
Direct Manufacturer Equivalent: SN74AUP1T34DCKR (Texas Instruments) — same logic function and package, active product status, reduced output drive current (6mA vs. 24mA), narrower supply voltage range (0.9V ~ 3.6V).
Similar Function, Alternative Package: 74AUP1T34GM,115 (Nexperia), 74AXP1T34GMH (Nexperia), 74AXP1T34GSH (Nexperia), 74AXP1T34GXH (Nexperia), SN74AUP1T34DSFR (Texas Instruments) — same logic function, different package geometries, varying electrical specifications.
Voltage Level Translator Variants: SN74AUP1T57DBVR, SN74AUP1T57DRYR, SN74AUP1T57DSFR (Texas Instruments) — different functional classification (voltage level translator vs. buffer), different electrical specifications, alternative packages.

Engineering Selection Recommendations
For Direct Replacement (Same Package, Same Footprint):
SN74AUP1T34DCKR (Texas Instruments) is the primary active-status equivalent. It maintains the 5-TSSOP/SC-70-5/SOT-353 package and push-pull output configuration. The reduced output drive current (6mA vs. 24mA) and narrower supply voltage range (0.9V ~ 3.6V vs. 0.9V ~ 4.5V) must be evaluated against application requirements. This part is active and RoHS3 compliant.
NLVSV1T34DFT2G (onsemi) provides parametric equivalence with identical electrical specifications and automotive qualification (AEC-Q100). The difference is packaging format (Tape & Reel vs. Cut Tape), which affects procurement and handling but not electrical performance.
For Alternative Package Designs:
74AUP1T34GM,115 (Nexperia) offers active product status with extended operating temperature range (-40°C to 125°C) but requires PCB redesign due to 6-XFDFN package. Output drive current is reduced to 4mA, and supply voltage range is narrower (1.1V ~ 3.6V).
SN74AUP1T34DSFR (Texas Instruments) provides active status in 6-XFDFN package with 6mA output drive and 0.9V ~ 3.6V supply range.
For Voltage Level Translation Applications:
SN74AUP1T57 series (DBVR, DRYR, DSFR variants) are voltage level translators with different functional architecture and dual supply voltage requirements (VCCA and VCCB). These are suitable only if the application specifically requires voltage level translation rather than simple buffering.
Obsolete Part Alternatives:
74AXP1T34 series (GMH, GSH, GXH variants from Nexperia) are obsolete and should be avoided for new designs unless existing inventory constraints require their use. These parts have reduced output drive current (12mA) and narrower supply voltage range (0.7V ~ 2.75V).
Frequently Asked Questions (FAQ)
Q: Can SN74AUP1T34DCKR directly replace NLSV1T34DFT2G without PCB changes?
A: Yes, both parts use the 5-TSSOP/SC-70-5/SOT-353 package with identical pinout. However, verify that the application can tolerate reduced output drive current (6mA vs. 24mA) and narrower supply voltage range (0.9V ~ 3.6V vs. 0.9V ~ 4.5V).
Q: What is the difference between NLSV1T34DFT2G and NLVSV1T34DFT2G?
A: Both parts are onsemi buffers with identical electrical specifications and package. The difference is packaging format: NLSV1T34DFT2G is Cut Tape (CT) & Digi-Reel®, while NLVSV1T34DFT2G is Tape & Reel (TR). NLVSV1T34DFT2G includes automotive qualification (AEC-Q100).
Q: Why do Nexperia 74AUP1T34 and 74AXP1T34 parts have different output drive currents?
A: The 74AUP series is designed for ultra-low power applications with 4mA output drive. The 74AXP series provides higher drive current (12mA) but operates at lower supply voltages (0.7V ~ 2.75V). Both are different product lines with different electrical characteristics.
Q: Can I use SN74AUP1T57 series as a substitute for NLSV1T34DFT2G?
A: No. SN74AUP1T57 is a voltage level translator with different functional architecture, dual supply voltage requirements, and single-ended output. It is not functionally equivalent to a buffer. Use only if your application specifically requires voltage level translation.
Q: What does "Obsolete" product status mean for the NLSV1T34DFT2G?
A: Obsolete status indicates the manufacturer has discontinued production. Existing inventory may be available from distributors, but long-term supply is not guaranteed. For new designs, select an active-status equivalent such as SN74AUP1T34DCKR or 74AUP1T34GM,115.
Q: Are all substitute parts RoHS3 compliant?
A: Yes. All parts listed in this reference are RoHS3 compliant and have MSL 1 (Unlimited) moisture sensitivity rating, meeting current environmental and reliability standards.
Q: If I need to change packages, which alternative offers the best performance match?
A: SN74AUP1T34DSFR (6-XFDFN package) provides the closest electrical match with 6mA output drive and 0.9V ~ 3.6V supply range. 74AUP1T34GM,115 (6-XFDFN package) offers extended temperature range (-40°C to 125°C) but with reduced output drive (4mA) and narrower supply voltage (1.1V ~ 3.6V).
