Hello!
On a page inside appnote AN3845 from Maxim back when they were still
making the DS2423 parts, the schematic shown includes a pair of
Schottky diodes, they were the BAT54 series. Also a pull-down resistor
of 1Meg.

Now I can certainly grok the reasoning behind the pull-down resistor
for the part to work properly, but what about the dual diodes? The
other problem is that these are of the small outline style, which
means they are available as surface mount styles. (They might be
available in the standard mountable rather than a surface mount style.
I've not checked further.)
