Transistor-Transistor Logic (TTL)

Transistor-Transistor Logic (TTL) is a digital circuit technology that uses bipolar junction transistors (BJTs) to perform logical operations like AND, OR, and NOT. In TTL circuits, transistors act as switches, controlling the flow of electrical signals to represent binary data—"0" and "1." This design allows for fast, reliable, and efficient processing of digital information. TTL was widely used in early computers and electronic devices, characterized by compactness and high switching speed. Today, it has been largely replaced by more advanced technologies, but it remains a foundational concept in digital electronics.
