The Microchip Digital temperature sensor particularly suited for low cost and small form-factor applications. Temperature data is converted from the on-board thermal sensing element and made available as an 8-bit digital word. Communication with the TC74 is accomplished via a simple 2-wire SMBus/I2C compatible serial port. This bus also can be used to implement multi-drop or multi-zone monitoring. The SHDN bit in the CONFIG register can be used to activate the low-power Standby mode.
