TC74A0-5.0VCTTR - Microchip Function Overview

The TC74A0-5.0VCTTR is a serially accessible tiny serial Digital Thermal Sensor for 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/second. During normal operation, the quiescent current is 200µA (typical). During standby operation, the quiescent current is 5µA (typical). The TC74 acquires and converts temperature information from its onboard solid-state sensor with a resolution of ±1°C. It stores the data in an internal register which is then read through the serial port.
