The DS1721U+T&R is a 2 wire digital thermometer and thermostat in 8 pin µSOP package. The 12 bit temperature readings which indicate the temperature of the device. Thermostatic settings and temperature readings are all communicated to/from the DS1721 over a simple 2 wire serial interface. No additional components are required, the device is truly a "temperature to digital" converter. The DS1721 has three address bits that allow a user to multidrop up to eight sensors along the 2 wire bus, greatly simplifying the bussing of distributed temperature sensing networks. 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 is equal to or below the user-defined temperature TL and allows for any hysteresis necessary. The active state of TOUT is configurable by the user.
