- I found a store that has Dallas iButton thermochrons in stock. After
my order today, they have about 7 left. You might want to check their
stock before placing your own order. These are not the extended-range
thermochrons that go to -55C, but only down to -40C.
The Maxim website says 3-13 weeks lead time required, depending on model.
