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 require-
ments for 600
鈩?900 鈩?/div>
resistive and complex imped-
ance termination applications. It interfaces the low-
voltage 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鈥攅xternal
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 package.
Two channels in a single package
Serial data interface
Per-channel powerdown
Low standby power (鈮?5 mW per channel)
Integrated protection
No external protection device required
Battery noise cancellation
Switchhook detector
Ring-trip detector
Switchhook and ring-trip detector self-test
Fault detector
Zero ring voltage cross detection
Three relay drivers per channel
44-pin, surface-mount, plastic package (PLCC)
