Part of the Microprocessors glossary: Transistor-transistor logic (TTL) is a digital logic design in which bipolar transistor s act on direct-current pulses. Many TTL logic gate s are typically fabricated onto a single integrated circuit (IC).
Electronic components are mostly industrial products, available in a singular form and are not to be confused with electrical elements, which are conceptual abstractions representing idealized electronic components. transistor is a semiconductor device used to amplify and switch electronic signals and electrical power. 1  Transistors. 2  Bipolar junction transistor (BJT, or simply transistor) â NPN or PNP. 3  Photo transistor â Amplified photodetector.
