Abstract :
A new high-voltage, dielectrically isolated, complementary bipolar technology has been used to integrate high-voltage functions of a subscriber line interface circuit (SLIC). This circuit, in conjunction with a complementary low-voltage junction isolated bipolar integrated circuit, implements most of the line interface functions required for digital telephone switches. Partitioning of the junctions is based on technology requirements, and the two chips are encapsulated in 28-pin package.
