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 datashdet state. Thus when an input is applied corresponding output pin drops down to zero there by enabling the load connected to complete its path.
