FEATURES
Unique 1-Wire
interface requires only one
port pin for communication
Derives power from data line (“parasite
power”)—does not need a local power supply
Multi-drop capability simplifies distributed
temperature sensing applications
Requires no external components
±0.5°C accuracy from –10°C to +85°C
Measures temperatures from –55°C to
+100°C (–67°F to +212°F)
9-bit thermometer resolution
Converts temperature in 750 ms (max.)
User–definable
non-volatile
temperature
alarm settings
Alarm search command identifies and
addresses devices whose temperature is
outside of programmed limits (temperature
alarm condition)
Ideal for use in remote sensing applications
(e.g., temperature probes) that do not have a
local power source

DESCRIPTION
The DS18S20-PAR digital thermometer provides 9–bit centigrade temperature measurements and has an
alarm function with nonvolatile user-programmable upper and lower trigger points. The DS18S20-PAR
does not need an external power supply because it derives power directly from the data line (“parasite
power”). The DS18S20-PAR communicates over a 1-Wire bus, which by definition requires only one
data line (and ground) for communication with a central microprocessor. It has an operating temperature
range of –55°C to +100°C and is accurate to
±0.5°C over a range of –10°C to +85°C.
Each DS18S20-PAR has a unique 64-bit identification code, which allows multiple DS18S20-PARs to
function on the same 1–wire bus; thus, it is simple to use one microprocessor to control many
DS18S20-PARs distributed over a large area. Applications that can benefit from this feature include
HVAC environmental controls, temperature monitoring systems inside buildings, equipment or
machinery, and process monitoring and control systems.
