You want both of your drivers to be off when idsabled so you would have to use a lot of logic there. Both drivers would need to be non-inverting in order for you to be able to disable them with and gates. Then you would need to invert the input of one and gate again.
This is serious complication and lots of unwanted delays. If I had no UCC's I would probably just run CW until I get some. Drivers are pin compatibile apart from enable.

Yep, from they have fast delivery so you can blow em' up twice as fast I did, the only thing which is annoying is that they only have the little SO-8 SMD packages. Have fun soldiering them

oh cr*p, there's no way I can solder this with a soldering gun I'll probably have to run halfwave CW, until I find a way how to interrupt the TC's

Last time I checked, TI will deliver DIP8, SOIC8 and MSOP8 UCC MOSFET drivers, all of which are possible to solder by hand with a fine tip.
P.S. Please don't over-exploit (exploit) the samples offered by TI. They are NOT 'free'. The samples you might receive are subsidized by the profit TI makes on the same chips that WE pay good money for.
If a group of regular abusers re-orders the chips without a followup purchase, it becomes uneconomical for TI to distribute samples of that chip, and they may stop offering them at any time.
At least try to make a quarter-effort not to blast them all by mistakes like "bumping the voltage knob".

Another way that I found easy is to get some copper stripboard and stick it to that, heres a pic of mine: Yes, I know it is wrong to exploit their free samples, the chances are that next time I am going to buy them along with a some other stuff.
