PBL38614-1 Subscriber Line Interface Circuit

The PBL 386 14/1 Subscriber Line Interface Circuit (SLIC) is a 90 V bipolar integrated circuit for use in ISDN Network Terminal Adapters and other short loop telecommunication equipment which often are remote powered, and by that, the available power is limited. The PBL 386 14/1 has been optimized for low total line interface cost, low power and requires a m.
