STLC3055 - ST Microelectronics

STLC3055 WLL & ISDN-TA SUBSCRIBER LINE INTERFACE CIRCUIT

The STLC3055 is a SLIC device specifically designed for WLL (Wireless Local Loop) and ISDNTerminal Adaptors. One of the distinctive characteristic of this device is the ability to operate with a single supply voltage (from +5.5V to +15.8V) and self generate the negative battery by means of an on chip DC/DC converter controller that drives an external MOS swi.
