Hello All!

I have a question about DSTINI1 schematics. I have searched archives,
but didn't find an answer. So, the question is: why DS2433 (U9)
is connected to non-buffered internal 1-Wire bus (INTOW), while DS2502 (U11) is
connected to buffered one (INTOWB)? Maybe the role of 2N7002 (Q4)
on INTOW is not to buffer this signal, but do to something else?
