Polarity
SCR (silicon controlled rectifier)
Gate – conducts when triggered by positive
voltage
• Transistor
– uses a small amount of voltage or electrical current to control a
larger change in voltage or current.
– Base, Emitter, Collector
– PNP, NPN
Integrated Circuits (IC’s)
• Basically a pkg of components
(programmed)
– TTL (Transistor-Transistor Logic)
– CMOS (Complimentary – Metal oxide
semiconductor)
– Plug into sockets soldered into circuit board
