The 74LVC2G07DW-7 is a dual supply 2-input NAND Gate with Schmitt-trigger inputs for use in applications depending on signal edge rate instead of signal level. The part is housed in a tiny SOT25 package. It contains two independent gates, each with two input terminals and one output terminal, that can be cascaded without connecting the supply voltage.

Application Field

The 74LVC2G07DW-7 is ideal for logic applications that have specific high-speed switching requirements, such as typically found in optical and magnetically enabled devices. It is often used in high-frequency digital circuits such as high-speed clock shaping, power management or sensing circuit. It is an ideal choice for many different types of application fields like:

• Portable Electronics
• Computer Peripherals
• Medical Equipment
• Consumer Electronics
• Vehicle Components and Electrical Motors

Working Principle

The 74LVC2G07DW-7 works based on the principle of differential input stage. The differential inputs greatly reduce the influence of external noise while still providing switching performance that is unaffected by a constant temperature level. There are two Schmitt-trigger inputs and a Schmitt-trigger action ensures that rapid rises and falls of the input signal are accurately converted into fast, clean and jitter-free output signals. This works even when power supply and ground swings occur.

The device\'s inputs are TTL compatible and feature high current protection, making them ideal for use in optocouplers, logic and automotive applications. Its low power consumption and minimum threshold levels result in the use of significantly reduced levels of current in the design of logic circuits. Plus, the part is designed to operate from a single +2.7V to 5.5V supply.

The part is designed to be as robust as possible with its 0.4V maximum low level voltage, making it suitable for use in harsh systems and environments including automotive and industrial applications. Its output voltage range is also greater than that of the supply voltage, furthering its suitability for high vibration, load-unbalanced or noisy environments.

The part is also fully characterized up to the maximum specified frequency (typically 1MHz). This allows it to operate at much higher frequencies than more general parts, which can be beneficial in certain applications. It can also provide a much higher level of noise immunity, making it suitable for use in delicate systems.

The 74LVC2G07DW-7 provides improved noise immunity and robustness due to its differential output stage. It also features an improved resistance to latch-up, which can be a problem in many applications. The device is highly reliable and is qualified to AEC-Q100 automotive reliability standards, allowing it to withstand harsher conditions and be used in more demanding environments.

Finally, the part includes protection diodes between input and output, and between the power pins, so it can be used in a variety of applications without requiring any external protection.
