A Darlignton pair is two transistors that act as a single transistor providing high current gain. Notify of all new follow-up comments Notify of new replies to all my comments.

Thus when an input is applied corresponding output pin drops down to zero there by enabling the load connected to complete its path. Property Data This page displays only the text of a material data sheet.

Quote and Order boards in minutes on: In this pair the current amplified by the first transistor is further amplified by the next transistor providing high current to the output terminal.

When no base voltage is applied that when is no signal is given to the input pins of the ICthere will be no base current and transistor remains in off state.
