The 74LVC1G07FW5-7 is a single-gate logic buffer that belongs to the Logic – Buffers, Drivers, Receivers, Transceivers family. It is designed to provide a high level of noise immunity due to its Schmitt trigger input which also increases the device’s tolerance of slow input rise and fall times. The logic buffer is optimized for typical voltage ranges between 1.65-3.6V, making it versatile enough to be used in a range of applications. This logic buffer is ideal for low-voltage logic buffering with 3-state output capability, and the standard ESD-protection of up to 2kV.

The 74LVC1G07FW5-7 features a low power consumption, making it a great choice for applications where power efficiency is essential. The low voltage of operation offers an extended range of operating temperatures from -40°C to +85°C, and the logic buffer is available in a range of packages for easy implementation in a variety of applications. Its widespread usage includes interfacing between buses, latching of address inputs as well as clock and data signals.

The 74LVC1G07FW5-7’s typical fan-in of 1 provides a very low input capacitance and features a low output glitch on the rising and falling edge of a signal. Its wide range of applications makes it suitable for low voltage, low power, and mixed signal design. The logic buffer can be used to drive up to seven higher logic device’s inputs in applications such as sequencers, multiplexers, encoders and decoders.

Working Principle: The 74LVC1G07FW5-7 logic buffer works on the principle of inverting logic, which is defined as a logic operation by which the input and output signals are opposites. A logic level of 0 at the input results in a logical level of 1 at the output, and vice versa. The 74LVC1G07FW5-7 features a single inverting stage that is composed of two transistors, making it capable of high-speed switching. The internal circuit uses N-Channel and P-Channel MOSFETs that form the inverting stage. When the signal applied to the gate of the N-MOSFET is below a certain threshold value, it will turn on and the output signal will be low.

The output is also protected by a pull-up internal circuit , which is composed of two transistors. The circuit is activated when the signal applied to the gate of the P-MOSFET is below the threshold voltage, which causes it to turn on and pull the output to a high state. This protects the output from the damaging effects of positive and negative power surges.

The 74LVC1G07FW5-7 logic buffer is an ideal and cost-effective solution for low power, low voltage, and mixed signal designs. It is also highly desirable for its low input and output capacitances and its three-state output for robust logic designs. In addition, its wide range of applications, including latching of address inputs, multiplexers, and clock and data signals, makes it suitable for a variety of applications.
