Thus when an input is applied corresponding output pin drops down to zero there by enabling the load connected to complete its path. We also ask that you refer to MatWeb’s terms of use regarding this information. We advise that you only use the original value or one of its raw conversions in your calculations datasheeh minimize rounding error.

This IC is widely used to drive high loads such Lamps, relays, motors etc. When high logic is fed to the input both the transistors begin to conduct providing a path to ground for the external load that the output is connected. Data sheets from materials that are no longer available remain in MatWeb to assist users in finding replacement materials.


Quote and Order boards in minutes on: 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.
