HC9P5502B-5 EIA/ITU PABX SLIC with 30mA Loop Feed

28 PIN PLCC 2 24 PIN DIP/SOIC 1 SYMBOL TIP DESCRIPTION An analog input connected to the TIP (more positive) side of the subscriber loop through a 150Ω feed resistor and a ring relay contact. Functions with the Ring terminal to receive voice signals from the telephone and for loop monitoring process.

HC-5502B Data Sheet February 1999 File Number 2884.5 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 batt.
