Description
The L7585G Full-Feature, Low-Power Subscriber
Loop Interface Circuit (SLIC) and Switch integrates
the battery feed, test access relay, and ringing relay
that are necessary to interface a codec to the tip and
ring of a subscriber loop into one low-power, low-cost
package. It is built using a 90 V complementary bipo-
lar (CBIC) process and a 320 V Bipolar-CMOS-
DMOS (BCDMOS) process. The device is available
in a 44-pin MQFP package.
The device can be connected directly to the Lucent
Technologies Microelectronics Group T7531/T7536
16-Channel Programmable Codec Chip Set without
the need for any ac interface components.
