Your side of the pond Newark definitely sell them, now they are tied 
up with Farnell they're a pretty good distributor in terms of what 
they carry. If you guys are used to the Newark catalogue you'll be 
blown away by the Farnell one <heh heh>. Unlike a lot of places 
Newark/Farnell sell in ones and twos, which can be more useful than 
being able to get them for half the price if you buy 250....

According to the specs the only difference is the noise level. Always 
use the TL07x instaed of the TL08x if they are both available for the 
same price, but even better, use the TL05x series, they are enhanced 
TL07x and only cents dearer.
