HC-5502B EIA/ITU PABX SLIC with 30mA Loop Feed The Intersil SLIC incorporates many of the BORSHT functions on a single IC chip. This includes DC battery feed, a ring relay driver, supervisory and hybrid functions. This device is designed to maintain transmission performance in the presence of externally induced longitudinal currents. Using the unique Intersil dielectric isolation process, the SLIC can operate directly with a wide range of station battery voltages. The SLIC also provides selective denial of power. If the PBX system becomes overloaded during an emergency, the SLIC will provide system protection by denying power to selected subscriber loops. The Intersil SLIC is ideally suited for the design of new digital PBX systems, by eliminating bulky hybrid transformers. Features • Capable of 12V or 5V (VB+) Operation • Monolithic Integrated Device • DI High Voltage Process • Compatible With Worldwide PBX Performance Requirements • Controlled Supply of Battery Feed Current for Short Loops (30mA) • Internal Ring Relay Driver • Low Power Consumption During Standby • Switch Hook, Ground Key and Ring Trip Detection Functions • Selective Denial of Power to Subscriber Loops Applications • Solid State Line Interface Circuit for Analog and Digital PBX Systems • Direct Inward Dial (DID) Trunks • Voice Messaging PBXs • Related Literature - AN549, The HC-5502S/4X Telephone Subscriber Line Interface Circuits (SLIC) - AN571, Using Ring Sync with HC-5502A and HC-5504 SLICs Part Number Information PART NUMBER TEMP.
