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.

The green package meets RoHS Directive 2002/95/EC of the

European Council to minimize the environmental impact of

electrical equipment.

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.

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

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

required)

Two on-chip relay drivers and snubber circuits

Space-saving package options (8x8 QFN)

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.
