Transistorlogik

Transistorlogik, also known as transistor-transistor logic (TTL) or more generally as semiconductor logic, refers to the design and implementation of digital logic circuits using transistors as the fundamental switching elements. Instead of mechanical switches or vacuum tubes, transistors are employed to represent binary states, typically 0 and 1. A transistor can be thought of as an electronically controlled switch. By controlling the voltage or current applied to its control terminal, the transistor can be made to either conduct or block electrical current, thereby switching between its ON (conducting) and OFF (blocking) states.

These switching actions are organized into logic gates such as AND, OR, NOT, NAND, and NOR gates. Each gate performs a specific Boolean function. For example, an AND gate outputs a high signal only if all its inputs are high. By combining these fundamental gates, more complex digital circuits can be constructed, forming the basis of all modern digital electronics. This includes microprocessors, memory units, and control systems found in computers, smartphones, and countless other devices. The miniaturization and speed offered by transistors have revolutionized electronics, enabling the development of incredibly powerful and compact digital systems.
