HC5526 Datasheet (Intersil Corporation) - ITU CO/PABX SLIC with Low Power Standby

HC5526, ITU CO/PABX SLIC with Low Power Standby

HC5526 Data Sheet October 1998 File Number 4151.6 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 Junct
