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.
