September 1997 PBL 3766, PBL 3766/6 Subscriber Line Interface Circuit Description The PBL 3766 Subscriber Line Interface Circuit (SLIC) is a monolithic integrated circuit, manufactured in 75 V bipolar technology.
The PBL 3766 SLIC facilitates the design of cost effective, high performance on-premises (ONS) analog line interface cards for PABX systems and terminal adapters.
Small package size and few required external components result in a miniaturized design.
The PBL 3766 programmable, constant current loop feed system can operate with battery supply voltages between -24 V and -58 V.
The SLIC incorporates loop current and ring trip detection functions as well as a ring relay driver.
