Data Sheet

File Number

ITU CO/PABX SLIC with Low Power
Standby
The HC5515 is a subscriber line interface circuit which is
interchangeable with Ericsson鈥檚 PBL3860 for distributed
central of鏗乧e 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 bene鏗乼 of the DI
process guarantees operation under adverse transient
conditions. This process feature makes the HC5515 ideally
suited for use in harsh outdoor environments.
