FEATURES
§ Temperature measurements require no
external components
§ 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 value (2-
byte transfer)
§ Wide power supply range (2.7V to 5.5V)
§ Converts temperature to digital word in 1
second
§ Thermostatic settings are user definable
and nonvolatile
§ Data is read from/written via a two–wire
serial interface (open drain I/O lines)
§ Applications include thermostatic
controls, industrial systems, consumer
products, thermometers, or any thermal
sensitive system
§ 8–pin DIP or SOIC package (150-MIL and
208-MIL)

DESCRIPTION
The DS1621 Digital Thermometer and Thermostat provides 9–bit temperature readings which indicate
the temperature of the device. The thermal alarm output, TOUT, is active when the temperature of the
device exceeds a user–defined temperature TH. The output remains active until the temperature drops
below user defined temperature TL, allowing for any hysteresis necessary.
User-defined temperature settings are stored in nonvolatile memory so parts may be programmed prior to
insertion in a system. Temperature settings and temperature readings are all communicated to/from the
DS1621 over a simple two–wire serial interface.
