[sdiy] TI SN74LS624N, worth buying?

[Bob K]

Thanks for the responses everyone.

Looks like I'll hold off on that particular chip and find new stuff.
Hell, I still have about 25 40106 that I need to figure out what I'm
going to do with.

That's the problem with beginners like me, I want to jump in as far as
I can with not knowing the basics.

Too many damn parts to buy.  They all look so pretty.
