FEATURES
• Unique 1–WireTM interface requires only one port pin
for communication
• Multidrop capability simplifies distributed temperature
sensing applications
• Requires no external components
• Can be powered from data line
• Zero standby power required
• Measures temperatures from –55°C to +125°C in
0.5°C increments. Fahrenheit equivalent is –67°F to
+257°F in 0.9°F increments
• Temperature is read as a 9–bit digital value.
• Converts temperature to digital word in 200 ms (typ.)
• User–definable, nonvolatile temperature alarm settings
• Alarm search command identifies and addresses
devices whose temperature is outside of programmed
limits (temperature alarm condition)
• Applications include thermostatic controls, industrial
systems, consumer products, thermometers, or any
thermally sensitive system
