Hi,
	I tried to use that chip as well.  I used the MJ10016
(if memory serves) Darlington.  I had some problems with
charge time and heat sinking.  Those trans. can get VERY hot - 
make sure you use good heat sinks.  I ended up not using
the MC3334P and just used the ignitors from an RX-7.
I'm still having some problems with my ignition (building
a distributorless ignition for my 1991 MR2 Turbo).  What
is your project about?
Thanks.
