Inputs (A1, A2, A3, A4, A5, A6): These are the logic input pins for each of the six inverters. Each of these pins accepts a digital signal (either high or low).
Outputs (Y1, Y2, Y3, Y4, Y5, Y6): These are the logic output pins for each of the inverters. The output will be the inverted form of the corresponding input (i.e., if the input is high, the output will be low, and vice versa).
GND (Pin 7): This is the ground pin. It should be connected to the ground of the circuit to complete the circuit and ensure proper functionality of the IC.
VCC (Pin 14): This is the supply voltage pin. It should be connected to a positive voltage source, typically +5V (or a value within the recommended voltage range for the device).
Circuit Principle
The MC74AC04 is a Hex Inverter IC, meaning it contains six individual inverters, which are logic gates that output the opposite (inverted) logic level from the input. The basic operation of an inverter is as follows:
If the input is logic high (1), the output will be logic low (0). If the input is logic low (0), the output will be logic high (1).These inverters can be used in various digital circuits for signal inversion, logic manipulation, and creating more complex circuits such as oscillators, logic controllers, and more.
