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.

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.
