Pinout Overview:
Pin Number Pin Name Pin Function Description 1 A Input Pin: The logic signal that is input into the buffer. It can be either high or low voltage, and this input is typically driven by other logic circuits. 2 GND Ground Pin: Provides the reference voltage for the circuit. This pin must be connected to the ground of the system to ensure proper operation. 3 Y Output Pin: Open-drain output pin that provides the buffered logic signal from the input. When the output is low, the pin is pulled to ground, and when high, it remains in a high-impedance state. 4 VCC Power Supply Pin: Provides power to the internal circuitry of the buffer. This pin should be connected to a stable power supply voltage. 5 NC No Connection Pin: This pin is not connected to any internal circuitry and can be left floating or connected to the ground in some designs.FAQ Section (20 Common Questions):
