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.
Due to size constraints, QFN devices are marked by omitting the
“Le” prefix and the performance grade dash character. For
example, Le79R79-1FQC is marked 79R791FQC.
The green package meets RoHS Directive 2002/95/EC of the
European Council to minimize the environmental impact of
electrical equipment.
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 Le79R79 Ringing SLIC 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, fiber-in-the-
loop, radio-in-the-loop, hybrid fiber/coax and video telephony
(home-side) boxes. The Le79R79 Ringing SLIC device can
provide sufficient voltage to meet the stringent LSSGR five-
ringer equivalent specification. Using a CMOS-compatible
input waveform and wave shaping R-C network, the Le79R79
Ringing SLIC device can provide trapezoidal wave ringing to
meet various design requirements.
See the
Le79R79 Block Diagram,
on page 4.
