nlsv2t244dmr2g

If you’re designing circuits that need logic-level shifting between different voltage systems, this chip is exactly what you’re looking for. It supports dual power supplies (VCCA and VCCB) from 0.9V all the way up to 4.5V, making it perfect for connecting low-voltage devices together. It’s fast too, with typical delays of just around 1.6 to 2.3 nanoseconds, so it works great even in high-speed applications.

You don’t need to worry about powering it up in any specific sequence—it handles voltage sequencing gracefully. Plus, it’s designed to handle accidental voltage spikes up to 4.5V safely, adding extra robustness. If the power goes down, the outputs automatically go high-impedance, protecting your circuits from damage.

Available in a small Micro8 (MSOP-8) package, it’s ideal when you’re tight on space, and it’s rated for industrial temperatures (−40°C to +85°C). This makes it perfect for mobile phones, industrial automation, consumer electronics, and communication devices.

When you’re wiring up the NLSV2T244DMR2G for voltage-level shifting, here’s what you need to keep in mind. First off, you’ve got two separate power pins—VCCA and VCCB—each supports voltages from 0.9V to 4.5V. The great part is, you don’t need a special startup order, but do add a small 0.1µF capacitor near each power pin for stable operation.

The signal pins, A1/A2 and B1/B2, are bidirectional, meaning you can choose which side sends or receives signals, based on your design. The OE pin is your output enable control—set it low to start data transfer, or high to put the outputs in a high-impedance state, ideal when sharing a bus with multiple devices.

Watch your input voltages carefully; never exceed the supply voltage on the corresponding side to avoid damaging the chip. Also, keep your PCB layout compact to reduce noise and interference, ensuring reliable, high-speed operation.

When you’re choosing a replacement chip, there are some key points you’ll want to keep in mind. First, double-check the voltage range—your new chip needs to match or exceed the original device’s operating voltage to ensure compatibility. Also, remember the original chip might have a fixed data direction, but replacements often have a configurable direction controlled by a DIR pin, so plan your logic accordingly.

Although the package might look identical, always verify each pin’s function carefully, since differences can cause unexpected issues. Speed matters too; make sure the new component supports your required data rates, ideally matching or outperforming your current chip.

Don’t forget ESD protection—if your project is in a noisy or industrial setting, choose a device with robust ESD ratings for better reliability. Finally, think practically about availability and cost; pick a readily available, cost-effective alternative to keep your project sustainable and economical. Always test thoroughly before finalizing the swap to ensure smooth operation.

If you take a close look at this circuit diagram, you’ll see exactly how the NLSV2T244DMR2G chip handles level shifting between two different voltage domains. Notice how clearly labeled V_CCA and V_CCB are—that tells you right away this chip is designed for connecting signals between different logic voltages.

You’ve got two separate channels here (A1→B1 and A2→B2), which match perfectly with the chip’s dual-channel setup. There’s also the OE pin, your output-enable control: keep OE low to pass signals through, or set it high to put the outputs into a safe high-impedance state, preventing any bus conflicts.

Another nice thing you’ll notice is that the circuit uses two inverters in a row per channel, giving you a clean, non-inverted output, exactly like the NLSV2T244DMR2G’s intended behavior. Make sure your dual power rails (V_CCA and V_CCB) match your application voltages, and you’ll have smooth, reliable signal translation every time.

When you’re connecting parts that run at different voltages, the NLSV2T244DMR2G chip is your go-to solution. It easily bridges low-voltage systems (like your 1.8V microcontrollers) and higher-voltage devices (like 3.3V sensors or displays), giving you reliable, clear signals without any inversion.

Inside, it has two separate channels—each handles one-way communication. When your input is high, the output stays high, and the same goes for low inputs. There’s an OE pin to control outputs; keep it low to let data flow, or high to safely disconnect outputs and avoid bus conflicts.

Another nice thing is you don’t need to worry about power-up sequences. Just connect each side’s voltage and add decoupling capacitors nearby. It’s also protected against accidental voltage spikes and power-down situations, keeping your hardware safe.

You’ll often use this chip in phones, FPGA interfaces, industrial controllers, or consumer electronics. Just remember: never feed an input higher than the supply voltage, and lay out your PCB carefully to maintain signal integrity.

1. Great for SPI Level Shifting

If you’re working with SPI communication—which has separate, single-directional data lines like MOSI and MISO—then the NLSV2T244DMR2G is a perfect choice. For example, maybe your MCU runs at 3.3V and your sensor at 1.8V; you can easily shift signals like MOSI, SCLK, or CS lines using this chip. Just keep in mind that MOSI and MISO need their own dedicated channels since they move data in opposite directions. But remember, if you’re dealing with single-wire bidirectional SPI, you’ll need a different solution because this chip only does one-way data flow.

2. Not Suitable for I²C Level Shifting (Important!)

However, you definitely shouldn’t use the NLSV2T244DMR2G for I²C interfaces. I²C requires signals to travel back and forth on the same line (both SDA and SCL), and this chip simply can’t do that. Instead, you’ll need specialized bidirectional translators like the NLSX3012 from onsemi, TI’s TXS0102, PCA9306, or the classic MOSFET-based level shifter using something like a BSS138 transistor.
