µPC7073 ANALOG SUBSCRIBER LINE LSI (BS-SLIC)
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.
FEATURES
• Single-chip, monolithic LSI (bipolar) • Constant-resistance feed or semi constant-current feed Note • 200-Ω feed, 400-Ω feed, or Tip-to-Ring pin feedou...
