I were able to buy 74ALS867 from distrubutor called Wyle Labs in Billerica, MA.
They send it to me in 2 days and they were the less expencive too. (compare to 
NewArk, Arrow and other big guys). You best bet would be to call to TI and ask
them who might carry this kind of IC. As about reasons to use 8-bit counter ins-
tead of 4-bit ones in my case it was the size of IC. 2 4-bit counters would 
take almost twice as much space as 1 8-bit counter and if you need lots of them
on one board...I am at home now and dont have address of Wyle Labs handy, so if
you can't find it yourself let me know and i'll find it when im at work.
