The 7404 is a digital logic integrated circuit containing six independent inverter (NOT) gates in a single package. It is part of the classic TTL (Transistor-Transistor Logic) family and operates from a standard 5V supply. The 7404 performs logical inversion, converting HIGH inputs to LOW outputs and vice versa, making it essential for signal inversion, logic buffering, pulse shaping, and timing circuits. With its standard DIP-14 package, it is ideal for breadboard prototyping, digital circuit design, and educational electronics.
