L8576B Dual Ringing SLIC

Features

Applications

■ Two SLIC channels for multiple tip/ring interfaces

■ POTS for ISDN

■ On-chip balanced ringing generator, no ring relay

required

■ Terminal adapters (TA)

■ Digital loop carrier (DLC) systems

■ PABX

■ Single battery operation or optional automatic bat-

tery switch

■ Quiet battery reversal for on-hook signaling

■ Disconnect state

Description

■ Distortion-free, on-hook transmission

■ 24 mA loop current limiter

The Agere Systems Inc. L8576B electronic dual sub-

scriber line interface circuit (SLIC) provides all the

functions that are necessary to interface a codec to

the tip and ring of a subscriber loop, integrating two

battery feeds and ringing generators in one low-cost

package. The L8576B device is optimized to meet

the needs of short loop, customer premises applica-

tions and features balanced ringing from the single

battery supply. The device is built using a 90 V com-

plementary bipolar (CBIC) process. It is available in a

44-pin PLCC package.

■ Ring trip detector

■ Switchhook detector

■ Immune to channel crosstalk and impulse noise

■ Allows rail overvoltages for ease of protection

■ Thermal protection

■ 44-pin, surface-mount, plastic package (PLCC)
