BIPOLAR ANALOG INTEGRATED CIRCUIT

The

µPC7073 is a BS-SLIC that can be used in analog subscriber circuits such as private branch exchangers

(PBXs) and switching equipment for central offices. It features two of the functions required for analog subscriber

circuits: subscriber line feed control and subscriber line supervision.

Use of the

µPC7073 in combination with a digital CODEC (µPD9903) can reduce the number of components

required in analog subscriber circuits.
