WebTransistor- Transistor Logic (TTL) 5. Emitter Coupled Logic (ECL) or Current Mode Logic (CML) 6. ... (NPN), is that HIGH at input causes output to be LOW (i.e. like a inverter). In the case of PNP transistor, the LOW at input causes output to be HIGH. Advantage: Less number of Transistors; Disadvantage: High Power Dissipation; WebSummary. Sink and Source are terms used to define the flow of direct current in an electric circuit. A sinking input or output circuit provides a path to ground for the electric load. A sourcing input or output provides the voltage source for the electric load. Logic is defined by the type of components in the circuit.
