Description:
The TC74 is a serially accessible digital temperature sensor that can determine temperatures in the range of 25°C to 85°C with ±2° absolute accuracy or 0°C to 125°C with ±3° absolute accuracy. Temperature information is retrieved from the TC74 via a two wire SMBus/I 2 C ? compatible interface. The TC74 represents the temperature as an 8-bit two?s complement signed integer that has a direct correspondence to the device?s temperature in degrees C resulting in a 1° temperature resolution. The TC74 is available in eight address versions so that eight devices can be monitored on the same two wire SMBus interface with no additional circuitry.
