* Legerity reserves the right to fulfill all orders for this device with parts

marked with the "Am" part number prefix, until such time as all inven-

tory bearing this mark has been depleted. It should be noted that parts

marked with either the "Am" or the "Le" part number prefix are equiva-

lent devices in terms of form, fit, and function. The only difference be-

tween the two is in the part number prefix appearing on the topside

mark.

DESCRIPTION

The Le79R101 Ringing SLIC device is a bipolar monolithic

SLIC that offers on-chip sinusoidal ringing. The sinusoidal

ringing waveform generated through the Le79R101 device has

an advantageously low distortion, and satisfies the traditional

ringing waveform requirements of small PBX, WLL, and

Pairgain applications. The Le79R101 Ringing SLIC device also

offers offset ringing and satisfies most phones that require an

offset from ring to tip during ringing.
