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. This IC is widely used to drive high loads such Lamps, relays, motors etc. These materials may be available by special order, in distribution inventory, or reinstated as an dayasheet product. Latest posts by Frank Donald see all. A Datashfet pair is two transistors that act as a single transistor providing high current gain.
