The TC74A5-3.3VCTTR is a serially accessible digital temperature sensor designed for low-cost and small form-factor applications. It converts temperature to an 8-bit digital word with a resolution of 1°C and communicates via a 2-wire SMBus/I2C compatible serial port. This specific model is optimized for a 3.3V supply voltage, operates over a temperature range of -40°C to +125°C, and features a maximum accuracy of ±2°C from +25°C to +85°C. The device supports a low-power standby mode with a typical current of 5 µA, while the typical operating current is 200 µA. Its small SOT-23-5 package makes it an ideal choice for implementing thermal management in systems like hard disk drives, PC peripherals, power supplies, and low-cost thermostat controls.
