HC5515 Datasheet (Intersil Corporation)

HC5515, ITU CO/PABX SLIC

HC5515 Data Sheet October 1998 File Number 4235.4 ITU CO/PABX SLIC with Low Power Standby The HC5515 is a subscriber line interface circuit which is interchangeable with Ericsson’s PBL3860 for distributed central ofﬁce applications.

Enhancements include immunity to circuit latch-up during hot plug and absence of false signaling in the presence of longitudinal currents.

The HC5515 is fabricated in a High Voltage Dielectrically Isolated (DI) Bipolar Process that eliminates leakage currents and de
