Product Overview

The TC74A0-5.0VAT is a tiny serial Digital Thermal Sensor, particularly suited for 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/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/second. Power consumption in only 200µA (5µA standby). Small size, low installed cost and ease of use make the TC74 an ideal choice for implementing thermal management in a variety of systems.
  • Outputs temperature as an 8-bit digital word
  • Simple SMBus/I²C™ serial port interface
