DESCRIPTION  
The DS1620 Digital Thermometer and Thermostat provides 9–bit temperature readings which indicate  
the temperature of the device. With three thermal alarm outputs, the DS1620 can also act as a thermostat.  
THIGH is driven high if the DS1620’s temperature is greater than or equal to a user–defined temperature  
TH. TLOW is driven high if the DS1620’s temperature is less than or equal to a user–defined temperature  
TL. TCOM is driven high when the temperature exceeds TH and stays high until the temperature falls  
below that of TL.
