描述 Description

General Description
The TC74 is a serially accessible digital temperature sensor particularly suited for low cost and small form factor applications. 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 2-wire 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 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.
