7400 series TTL

The 7400 series TTL (Transistor-Transistor Logic) is a collection of integrated circuits used to perform basic electronic functions like AND, OR, and NOT operations. Made from tiny transistors on a chip, these circuits process digital signals, typically represented as high (1) or low (0) voltage levels. They are foundational in digital electronics, enabling computers and other devices to perform logical tasks reliably and efficiently. The 7400 series has been a standard building block since the 1960s, known for durability, speed, and ease of integration into larger electronic systems.
