[En-Nut-Discussion] Ethernut and LVTTL

I want to use an ethernut to interface with the "reset" and "clock"
pins of 16 LVTTL chips in parallel. and also to the "data in" of the
first chip (which pushes the data out 2 clk cycles later to the next
chip) The chip has an absolute maximum of ~3.6V on its input pins.
1.)Do I need a level converter to connect the ethernut output ports
to the input ports of this chip?
2.)Is the ethernut fan-out capable of driving 16 LVTTL chips' input
lines (or 32?) in parallel?
3.)Will the ethernut recognize the 3.3V LVTTL High signal? It should
recognize anything above 2V as high, am i correct?
thanks!
