DESCRIPTION

The DS75 2–wire thermal watchdog provides 9–bit temperature readings which indicate the temperature of the device. Thermostat settings and temperature readings are all communicated to/from the DS75 over a simple 2–wire serial interface. No additional components are required; the device is truly a “temperature–to–digital” converter
