ITU CO/PABX SLIC with Low Power
Standby
The HC5526 is a subscriber line interface circuit that is
compliant with CCITT standards. Enhancements include
immunity to circuit latch-up during hot plug and absence of
false signaling in the presence of longitudinal currents.
The HC5526 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 (JI) 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 HC5526 ideally
suited for use in harsh outdoor environments.
