HC5523, LSSGR/TR57 CO/Loop Carrier SLIC with Low Power Standby

HC5523 Data Sheet October 1998 File Number 4144.5 LSSGR/TR57 CO/Loop Carrier SLIC with Low Power Standby The HC5523 is a subscriber line interface circuit which is interchangeable with Ericsson’s PBL3764A/4 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 HC5523 is fabricated in a High Voltage Dielectrically Isolated (DI) Bipolar Process that eliminates leaka
