SN74LVC1G125DBVR Introduction

If you want a small and effective way to translate voltage levels and buffer signals, the SN74LVC1G125DBVR is what you need. This single-line driver and bus buffer gate has a wide VCC operating range, a high output drive, and low power usage. This makes it perfect for a wide range of applications. The SN74LVC1G125DBVR is a versatile and safe choice for signal conditioning, voltage translation, and digital signal processing. So why accept less? Use the SN74LVC1G125DBVR to get the job done right.


The input voltage range for this bus buffer gate is 1.65 V to 5.5 V VCC. The SN74LVC1G125 is a three-state, single-line motor driver. The output is disabled when the OE input is set to a high value. The CMOS device offers low idle power consumption and high output drive over a wide range of VCC. The SN74LVC1G125 is available in various packages, including the ultra-compact DPW version, which has a body size of 0.8 mm and 0.8 mm.

Detailed Description

The Boolean function Y = A is done by the SN74LVC1G125 device, which has one buffer gate device with an output allow control. This device meets all the requirements for apps that use Ioff to power down partially. When the device is turned off, the Ioff electronics turn off the outputs. This keeps current from flowing back through the device and doing damage.

To keep OE in a high-impedance state when the power is turned on, or off, a pullup resistor should connect it to VCC. The minimum value of the resistor depends on how much current the driver can sink. The DPW package technology is a big step forward in how ICs are put together. Its tiny 0.64 mm square footprint saves a lot of boardrooms compared to other options. It also keeps the traditional 0.5 mm lead pitch, which makes it easy to make.

Operating characteristics

The SN74LVC1G125DBVR works with voltages between 1.65 and 5.5 volts and temperatures between -40°C and +125°C. The device can sink or source up to 32 mA of current and has an average supply current of 1.2 mA at 3.3 volts. This makes it a good choice for driving a wide range of loads.

The high power drive strength is among the best things about the SN74LVC1G125DBVR. This means it can drive different loads, including reactive ones, without affecting the signal quality. The device also has a low static power dissipation, which is important for lowering power use and extending the life of batteries in portable devices.

The output-enable (OE) input can turn off the 3-state output, another important part of how the SN74LVC1G125DBVR works. This feature gives you more control over how signals are routed and isolated. It can also help save power by separating the output from the input when it’s unnecessary.

Overall, the SN74LVC1G125DBVR is a flexible and effective device that can be used in many ways. Its high output drive strength and low power loss make it a good choice for portable and battery-powered devices. Its 3-state output and ability to translate voltage levels in both directions make it useful for any circuit design.

Application and Implementation

● Application Information

As an output-enabled buffer with a high output drive, like in an LED application, the SN74LVC1G125 device is a high-drive CMOS device. It is ideal for driving many outputs and suitable for high-speed applications up to 100 MHz because it can provide 24 mA of drive current at 3.3 V. It can translate up to VCC because the inputs can handle 5.5 V.

● Design Requirements

It has a balanced output drive and uses CMOS technology. Bus contention should be avoided since it can cause currents to flow over permitted limits. Routing and load conditions should be considered to avoid ringing because the high drive will also create quick edges into mild loads.

Power Supply Recommendations

A suitable bypass capacitor should be present on each VCC pin to avoid power disturbances. A 0.1-F capacitor is advised for devices with a single supply, and if there are several VCC pins, a 0.01-F or 0.022-F capacitor is advised for each power pin. Parking many bypass caps to block out various noise frequencies is acceptable. Capacitors of 0.1-F and 1-F are frequently used in parallel. The bypass capacitor should be mounted as close as feasible to the power pin for best results.


● Layout Guidelines

Inputs should never float when using gadgets with more than one bit of logic. Digital logic devices often have functions or parts of functions that aren’t used. For example, only two of a triple-input AND gate’s inputs are used, or only three of the four buffer gates are used. These input pins shouldn’t be left unconnected because the undefined voltages at the outside connections lead to undefined operating states.

Package Options

The SN74LVC1G125DBVR comes in a number of different packages, including the ultra-small DPW package, whose body is only 0.8mm x 0.8mm. There are also the SOT-23, SC-70, SOT-353, and X2SON packages.

Depending on the application and design requirements, each package choice has its own pros and cons. For example, the SOT-23 package is a common surface-mount package that is easy to find and use. The X2SON package, on the other hand, is a very small package that works well in designs with limited room.

The ultra-small DPW package works well with limited room, like portable devices or wearables. This choice for a package has a small footprint and a low profile, which makes it easy to use in small designs. But the small size of the package can make it hard to handle and put together, which may be something that some makers think about.

In general, the choice of package option for the SN74LVC1G125DBVR will depend on several things, such as what the application needs, how much room is available on the board, and how easy it is to put together. Before making a final choice, designers should consider each package option carefully and consider its pros and cons.


In conclusion, the SN74LVC1G125DBVR is an important device for engineers who want to build circuits that need a strong output drive, voltage level translation in both directions and low power loss. It can be used for signal filtering, voltage translation, and digital signal processing, among other things. The device comes in different packages, and choosing which one will rely on the application’s needs.
