The Dallas DS1620 is digital and also has set point outputs for HVAC
control. The digital comm is not async data. On a past design, I used the
DS1620 to sense temp then I controlled the contrast on an LCD for good
reading from -20 to 160F.

Check ECH for bit banged serial comm. You can easily get 9600 from any 4Mhz
part.
