Product Summary

The STLC3055QA7N is a WLL & ISDN-TA subscriber line interface circuit specifically designed for WLL (Wireless Local Loop) and ISDN-Terminal 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 externalMOS switch.
