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 device latch-up problems normally associated with junction isolated ICs. The elimination of the leakage currents results in improved circuit performance for wide temperature extremes. The latch free benefit of the DI process guarantees operation under adverse transient conditions.
