GENERAL DESCRIPTION
Temperature data is converted from the onboard thermal sensing element and made available as an 8-bit digital word. Communication with the TC74 is accomplished via a 2wire SMBus/I2C™ compatible serial port. Temperature resolution is 1°C. Conversion rate is a nominal 8 samples/sec. Power consumption is only 200µA typ, (5µA Standby, 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.
