Advance Data Sheet March 1997 L8575 Dual-Resistive, Low-Cost Subscriber Line Interface Circuit (SLIC) Features s s s s s s s s s s s s s s Description The L8575 is a dual-resistive, low-cost subscriber line interface circuit (SLIC) that is optimized to meet both ITU-T recommendations and LSSGR requirements for 600 Ω/900 Ω resistive and complex impedance termination applications.
It interfaces the lowvoltage circuits on an analog line card to the Tip and Ring of two subscriber loops.
The L8575 does not supply dc current to the subscriber loops—external resistors are used for this purpose.
The device is built using a 90 V complementary bipolar (CBIC) process and is available in a 44-pin PLCC...
