Product details
Overview
NLVSV1T34DFT2G from onsemi is a 1-bit dual-supply non-inverting level translator enabling bidirectional voltage translation between 0.9 V and 4.5 V rails. It supports independent VCCA (input-side supply) and VCCB (output-side supply), delivers propagation delay as low as 1.6 ns at 4.5 V, maintains power-off high-impedance I/O, and operates across −40 °C to +85 °C - used in mobile phone baseband-to-RF interface bridging.
For engineers reviewing the NLVSV1T34DFT2G datasheet, pinout, applications, or equivalent options, key selection criteria include dual-rail sequencing tolerance, sub-2 ns propagation delay at 3.3 V, OVT protection up to 4.5 V, ultra-low quiescent current (<4.0 µA total ICCA+ICCB), and SC-88A package compatibility with space-constrained portable designs.
Technical Context
The NLVSV1T34DFT2G implements passive transistor-based level shifting without internal logic or direction control pins. Its architecture allows either VCCA or VCCB to power up first without latch-up or damage, and both supplies can be independently powered down while maintaining high-impedance I/O states.
Input A and output B are unidirectionally coupled through a transmission-gate-like structure, supporting non-inverting translation only. The device exhibits balanced tPLH/tPHL delays and includes overvoltage-tolerant (OVT) input/output buffers rated to 4.5 V regardless of supply voltage - critical for mixed-voltage SoC interconnects.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCCA / VCCB Range | 0.9 V to 4.5 V - enables translation between sub-1 V logic and 3.3 V/4.5 V interfaces without external biasing |
| Propagation Delay (A→B) | 1.6 ns min / 3.3 ns max at 4.5 V - supports >200 MHz signal rates in active mode |
| IOFF Leakage (Power-Off) | <5.0 µA - prevents back-driving and cross-rail contention when one supply is off |
| VIH/VIL Thresholds | VIL = 0.1×VCCA (min), VIH = 0.9×VCCA (max) - ensures robust noise margin across all rail combinations |
| IOH/IOL Drive Strength | ±24 mA at 3.0 V - sufficient to drive 50 Ω transmission lines or fan-out to multiple CMOS inputs |
| Quiescent Current (ICCA+ICCB) | <4.0 µA - enables always-on level translation in battery-powered sleep modes |
| ESD Rating (HBM) | >3000 V - meets IEC 61000-4-2 Level 3 for handheld device front-end interfaces |
Pinout & Package
NLVSV1T34DFT2G uses the SC-88A (SOT-353/SC-70) 5-pin package (Case 419A-02), measuring 2.0 mm × 2.1 mm × 0.9 mm with 0.65 mm lead pitch. Pin 1 is marked with a dot; the package is Pb-free and RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCCB | Output port supply | Provides power to output buffer; sets VOH/VOL levels and defines B-port voltage domain |
| B | Translated output | Non-inverted logic-level replica of A referenced to VCCB; OVT-rated to 4.5 V |
| VCCA | Input port supply | Biases input stage and defines VIH/VIL thresholds; independent sequencing with VCCB |
| A | Logic input | Accepts 0.9–4.5 V signals; internally translated to VCCB domain without direction control |
| GND | Reference ground | Common return path for both supply domains; must be connected before applying VCCA or VCCB |
Key Features
| Feature | Design Value |
|---|---|
| Non-preferential supply sequencing | VCCA and VCCB may power up/down in any order - eliminates need for power-rail supervisors or sequencing ICs |
| Power-off high-impedance I/O | Both A and B enter Hi-Z state when either VCCA or VCCB = 0 V - prevents bus contention in partial-power-down systems |
| OVT protection on all pins | Withstands 4.5 V applied to A or B regardless of VCCA/VCCB - enables safe interfacing with higher-voltage peripherals |
| Ultra-low static power | Total ICCA + ICCB < 4.0 µA across full voltage/temperature range - extends battery life in always-on sensor hubs |
| AEC-Q100 qualified (Grade 2) | Rated for −40 °C to +105 °C operation and automotive PPAP - suitable for infotainment and ADAS domain controllers |
Applications
| Mobile Baseband–RF Interface | Wearable Sensor Hub Interconnect |

Equivalent & Alternatives
The following parts are listed as comparable options for similar level translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TXS0101DCKR | Single-bit auto-direction sensing; requires no direction pin but adds ~10 ns delay; higher ICC (10 µA typical) | Supports true bidirectional data (e.g., I²C) without external control; less suitable for high-speed unidirectional SPI | Select when bidirectional protocol support is required and 10 ns added delay is acceptable |
| NLSX3012MUTAG | 2-bit translator; same SC-88A package; lower drive strength (±8 mA); wider VCCA/VCCB range (0.65–4.5 V) | Optimized for multi-line interfaces like SDIO or parallel sensor buses; not pin-compatible with NLVSV1T34DFT2G | Select when consolidating multiple level-shifted signals into one package and lower drive is sufficient |
Compared with TXS0101DCKR and NLSX3012MUTAG, the NLVSV1T34DFT2G offers the lowest propagation delay and lowest quiescent current in SC-88A form factor, making it optimal for high-speed, low-power unidirectional signal routing where direction control is externally managed.

FAQ
What is the maximum operating temperature for NLVSV1T34DFT2G?
The NLVSV1T34DFT2G is rated for operation from −40 °C to +85 °C under standard conditions, and its NLV prefix indicates AEC-Q100 Grade 2 qualification extending thermal reliability to +105 °C ambient - verified per test condition TA = +105 °C in the official datasheet.
Does NLVSV1T34DFT2G require a direction control pin?
No, the NLVSV1T34DFT2G is a non-inverting unidirectional translator with fixed A→B signal flow and no direction control pin. Its architecture relies on internal pass-gate biasing, eliminating external control logic and simplifying PCB layout versus bidirectional alternatives like TXB010x series.
Can NLVSV1T34DFT2G translate between 0.9 V and 4.5 V simultaneously?
Yes - the NLVSV1T34DFT2G supports VCCA = 0.9 V and VCCB = 4.5 V (or vice versa) per its recommended operating conditions. Input thresholds scale with VCCA (e.g., VIH = 0.9×VCCA), and output levels track VCCB, enabling full-range translation without external components.
Is NLVSV1T34DFT2G pin-compatible with other NLSV1T34 variants?
No - NLVSV1T34DFT2G uses the SC-88A (5-pin) package, whereas UDFN6 and ULLGA6 variants have 6 pins and different pinouts (e.g., NC pin present). Only SC-88A-marked parts (DFT2G suffix) share identical pin assignment and footprint; mixing packages requires layout revision.
What is the input capacitance of NLVSV1T34DFT2G?
The NLVSV1T34DFT2G has a typical I/O pin input capacitance (CI/O) of 5.0 pF at VCCA = VCCB = 3.3 V, as measured per JEDEC JESD22-B111. This low capacitance minimizes signal loading on high-speed source drivers and preserves edge integrity in >100 MHz applications.
