HC5523
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 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. This process feature makes the HC5523 ideally
suited for use in harsh outdoor environments.
