PBL3766 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 ponents result in a miniaturized design.
