SN74LVC2G07DCKR Introduction

The SN74LVC2G07 is a dual buffer and driver that works with a VCC supply voltage of anywhere from 1.65 V to 5.5 V. Because it has an open-drain output, it can be used for both active-low wired-OR and active-high wired-AND operations. This device can translate up and down; at its most powerful, it can sink up to 32 mA. It also has Ioff circuitry, which turns off the outputs when the power is turned off. This keeps current from going back through the device, which could be dangerous.

The SN74LVC2G07 was built with NanoFree package technology, a major step forward in developing IC packaging technologies. This device is perfect for applications that need to turn off part of the power, and it only uses up to 10 A ICC of power. It also has a charge controller built right in. The part also has a fast tpd of 3.7 nanoseconds when running at 3.3 volts, and it can work with VCC as high as 5 volts. According to JESD 78, Class II, the latch-up performance of the SN74LVC2G07 is more than 100 mA. This makes it a great choice for high-drive CMOS applications like LED driver applications and wired-OR/AND operations.

SN74LVC2G07DCKR Description

This dual buffer and driver can be used with VCC voltages between 1.65 V and 5.5 V. You can use the active-low wired-OR and active-high wired-AND features of the SN74LVC2G07 device by connecting its open-drain output to other open-drain outputs. This device’s output has an open drain. 32 mA is the most current that can be taken from the sink.

Since it uses the die as the package, the NanoFree package technology is a big change in how integrated circuits (ICs) are packaged. All of the requirements for applications that use Ioff to do a partial power-down are met by this device. When the device is turned off, all of the outputs are turned off by the Ioff circuitry. This keeps current from flowing back through the device, which could be dangerous.

Detailed Description

The SN74LVC2G07 is a dual open drain buffer that can sink 32 mA of current. This device meets all the requirements needed to be used in Ioff-based applications that use partial power down. When the power is turned off, the Ioff circuitry stops the outputs to keep electricity from flowing back through the device and doing damage.

Feature Description

Because this device has an open-drain layout, it can’t generate its output drive current. Instead, it needs pullup resistors to keep the “high” bus state. It can only make the bus move slower. In the “Hi-Z” state, the SN74LVC2G07 acts like an open circuit, so an external pull-up can pull the bus to its maximum potential. Because of this, the pull-up voltage is what determines the output level. Because of this, the SN74LVC2g07 can be used for either up or down translation. The device can draw 24 mA when running at 3 V and keep its output voltage (VOL) at or below 0.55 V.

Application Information

The high-drive CMOS chip SN74LVC2G07 is versatile. It can generate a high-output driving buffer for LEDs. It can sink 32 mA of current at 4.5 V, which makes it a great part of high-drive and wired-OR/AND operations. Since the inputs can handle up to 5.5 V, you can translate either up to VCC or down to VCC.

Power Supply Recommendations

The power supply can be set to any voltage between the minimum and maximum supply voltage ratings. Each VCC pin needs to have a good bypass capacitor so that power problems don’t happen. It is recommended that devices with a single power supply use a capacitor with 0.1 microfarads of capacitance. Devices with multiple VCC pins should use a capacitor with either 0.01 microfarads or 0.022 microfarads for each power pin. Parallel bypass capacitors can eliminate noise at different frequencies. People often use capacitors with values of 0.1 uF and 1 uF in parallel. It is recommended that the bypass capacitor be installed in a location that is geographically close to the power pin to get the highest level of performance feasible.


● Layout Guidelines

When working with devices that use more than one bit of logic, there should be no such thing as a “floating input.” A lot of the time, only part of a digital logic device is used. For example, only two of the three inputs of a three-input AND gate or three of the four inputs of a four-input buffer gate are used. If you don’t connect the input pins, the undefined voltages at the external connections will cause the input pins to go into an undefined state. The rules that always apply are written out below. In digital logic devices, all inputs that aren’t being used need a high or low bias to keep them from “floating.” The logic level of any unused input should depend on how the device is meant to be used. Most of the time, they’ll be connected to GND or VCC, depending on what works best or is easiest to get to.


In conclusion, the SN74LVC2G07DCKR buffer and line driver are a great way to boost signals and control how much power they use. This device is great for many uses because its output is open drain and can work in various temperatures. It is also easy to assemble because it is shipped on tape and reel.
