[TenTec] KR-5 keyer

[Tom Sessions]

I am restoring an old Ten-Tec keyer.  The unit has one IC, an LU322B.

Can anyone tell me what this IC is, and more importantly direct me to a data
sheet or pinout diagram for it.  I have tried searching Google for this data
but had no luck.  I am trying to find an equivalent IC in thee Allied or
Mouser catalogs, but do not know what to look for.

Thanks / 73
