1. Zarlink reserves the right to fulfill all orders for this device with  
parts marked with the "Am" part number prefix until all inventory  
bearing this mark has been depleted. Note that parts marked with  
either the "Am" or the "Le" part number prefix are equivalent  
devices in terms of form, fit, and function—the prefix appearing on  
the topside mark is the only difference.

2. The green package meets RoHS Directive 2002/95/EC of the  
European Council to minimize the environmental impact of

FEATURES  
„ Ideal for ISDN-TA and set top applications  
„ On-chip ringing with on-chip ring-trip detector  
„ Low Standby state power  
3. Due to size constraints, QFN devices are marked by omitting the  
“Le” prefix and the performance grade dash character. For  
example, Le79R70-1QC is marked 79R701QC.  
4. For delivery using a tape and reel packing system, add a "T" suffix  
to the OPN (Ordering Part Number) when placing an order.

DESCRIPTION  
The Le79R70 Ringing Subscriber Line Interface Circuit  
(RSLIC) device is a bipolar monolithic SLIC that offers on-chip  
ringing. Designers can achieve significant cost reductions at  
the system level for short-loop applications by integrating the  
ringing function on chip. Examples of such applications would  
be ISDN Terminal Adaptors and set top boxes. Using a CMOS-  
compatible input waveform and wave shaping R-C network,  
the Le79R70 Ringing SLIC device can provide trapezoidal  
wave ringing to meet various design requirements.  
„ Tip Open state for ground-start lines  
„ Internal VEE regulator (no external –5 V power supply  
required)  
„ Two on-chip relay drivers and snubber circuits  
„ Space-saving package options (8x8 QFN)  
See the Le79R70 Block Diagram, on page 3.
