1. Due to size constraints, QFN devices are marked by omitting the

“Le” prefix. For example, Le79R241QC is marked 79R241QC.

2. The green package meets RoHS Directive 2002/95/EC of the Eu-

ropean Council to minimize the environmental impact of electrical

equipment.

•

Selectable off-hook and ground-key

thresholds

3. For delivery using a tape and reel packing system, add a "T" suffix

to the OPN (Ordering Part Number) when placing an order.

Description

Intelligent thermal management

The Le79R241 Intelligent Subscriber Line Interface

Circuit (ISLIC™) device, in combination with a VE790

series ISLAC™ device, implements the telephone line

interface function. This enables the design of a low

cost, high performance, fully software programmable

line interface for multiple country applications

worldwide. All AC, DC, and signaling parameters are

fully programmable via microprocessor or GCI

interfaces on the VE790 series ISLAC device.

Additionally, the Le79R241 ISLIC device has

integrated self-test and line-test capabilities to resolve

faults to the line or line circuit. The integrated test

capability is crucial for remote applications where

dedicated test hardware is not cost effective.

•

Compatible with inexpensive protection networks

•

Accommodates low tolerance fuse resistors or

PTC thermistors

Metering capable

•

12 kHz and 16 kHz

Smooth polarity reversal

•

Tip-open state supports ground start signaling

Integrated test load switches/relay drivers

5 REN with DC offset trapezoid.

•

For US standard:

drives ring up to 4.4 kft of 26 gauge wire.

drives ring up to 7 kft of 24 gauge wire.

For European (British) standard:

drives ring up to 1.7 km of 0.5 mm copper cable.
