Looks like the difference (for both transceivers) is the presence of an 
inhibit pin.

I usually use mouser.com when I buy the small quantity of parts I need 
for my projects. I see $1.12 for quantity 100 for the 8 pin version with 
~2K in stock. Looks like the reel quantity is 3000 so they are selling 
off their last reel. The 8 pin variants are all out of stock with 
impressive 60+ week lead times (and ~60K parts on order!) The NCV7356 is 
out of stock for both flavors and look more expensive.
