Product Overview
The TC74A3-5.0VAT is a serially accessible Digital Temperature Sensor particularly suited for in which, temperature data is converted from the onboard thermal sensing element and made available as an 8-bit digital word. Communication with the device 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.
- 8 Samples per second nominal conversion rate
- 200µA (typical) Normal operation quiescent current
- 5µA (typical) Standby operation, quiescent current
