Here is a detailed explanation of the pin functions and specifications for the SN74LVC1G17DBVR in a SOT-23-5 package.
Pinout (5 pins in total): Pin Number Pin Name Function Description 1 A Input pin (logic input for the inverter gate) 2 GND Ground pin (used to connect the component to the circuit ground) 3 VCC Supply voltage pin (connected to power supply) 4 Y Output pin (inverted logic output of input A) 5 NC No connection (reserved, typically not used for internal circuitry) Pin Descriptions:Pin 1 (A): The input of the inverter gate. It receives the logic signal that is going to be inverted. The input signal can be either a logic high (1) or low (0), and the output will be the opposite state.
Pin 2 (GND): This is the ground pin, where the IC is connected to the common ground of the circuit. It is essential for proper operation and signal reference.
Pin 3 (VCC): This is the power supply pin for the IC. It typically connects to the positive supply voltage in the circuit, often at 2.7V to 3.6V for low-voltage CMOS logic circuits.
Pin 4 (Y): The output pin of the inverter. This pin produces the inverse of the logic level applied to Pin 1 (A). If Pin 1 is high (1), this pin will output low (0), and vice versa.
Pin 5 (NC): This pin is not connected to any internal part of the IC. It is a no-connect pin, often used for mechanical or packaging reasons.
Circuit Principle:
The SN74LVC1G17 is a basic NOT gate. It takes a single input (A) and outputs its inverse (Y). The gate operates based on CMOS technology, offering high-speed operation and low power consumption. The output (Y) will always reflect the opposite of the logic level presented at the input (A).
