The DS1620 Digital Thermometer and Thermostat
provides 9-bit temperature readings which
indicate the temperature of the device. With
three alarm outputs, the DS1620 can also act as
a thermostat. T(HIGH) is driven high if the
DS1620's temperature is greater than or equal
to a user-defined temperature TH. T(LOW) is driven
high if the DS1620's temperature is less than or
equal to a user-defined temperature TL. T(COM) is
driven high when the temperature exceeds TH
and stays high until the temperature falls below
that of TL.
