In this pair the current amplified by the first transistor is further amplified by the next transistor providing high current to the output terminal.

Click here to view all the property values for this datasheet as they were originally entered into MatWeb.

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. Thus when an input is applied corresponding output pin drops down to zero there by enabling the load connected to complete its path. These materials may be available by special order, in distribution inventory, or reinstated as an 28033a product. We advise that you only use the original value or one of its raw conversions in your calculations to minimize rounding error.
