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. Please contact us at webmaster matweb.

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

We advise that you only use the original value or one of its raw conversions in your calculations to minimize rounding error. Data sheets from materials that are no longer available remain in MatWeb to assist users in finding replacement materials.
