    Tiny Serial Digital Thermal Sensor
    Features General Description Digital Temperature Sensing in SOT-23-5 or
    TO-220 Packages Outputs Temperature as an 8-Bit Digital Word Simple SMBus/I2Cв„ў Serial Port Interface Solid-State Temperature Sensing:
    -В±2В°C (max.) Accuracy from +25В°C to +85В°C
    -В±3В°C (max.) Accuracy from 0В°C to +125В°C Supply Voltage of 2.7V to 5.5V Low Power:
    -200 ВµA (typ.) Operating Current
    -5 ВµA (typ.) Standby Mode Current The TC74 is a serially accessible, digital temperature
    sensor particularly suited for low cost and small formfactor applications. Temperature data is converted from
    the onboard thermal sensing element and made
    available as an 8-bit digital word. Applications Thermal Protection for Hard Disk Drives
    and other PC Peripherals PC Card Devices for Notebook Computers Low Cost Thermostat Controls Power Supplies Thermistor Replacement Package Types Communication with the TC74 is accomplished via a 2wire SMBus/I2C compatible serial port. This bus also
    can be used to implement multi-drop/multi-zone
    monitoring. The SHDN bit in the CONFIG register can
    be used to activate the low power Standby mode.
    Temperature resolution is 1В°C. Conversion rate is a
    nominal 8 samples/sec. During normal operation, the
    quiescent current is 200 ВµA (typ). During standby
    operation, the quiescent current is 5 ВµA (typ).
    Small size, low installed cost and ease of use make the
    TC74 an ideal choice for implementing thermal
    management in a variety of systems. Functional Block Diagram Internal Sensor
