Microchip (TC74A0-3.3VAT) Temperature Sensor IC, Digital, ± 3°C, 0 °C

Temperature Sensor IC, Digital, ± 3°C, 0 °C, +125 °C, TO-220, 5 PinsProduct OverviewThe TC74A0-3.3VAT is a serially accessible tiny serial Digital Thermal Sensorfor small form-factor applications. Temperature data is converted from theonboard thermal sensing element and made available as an 8-bit digital word.Communication with the TC74 is accomplished via a 2-wire SMBus/I²C compatibleserial port. This bus also can be used to implement multi-drop/multi-zonemonitoring. The SHDN bit in the CONFIG register can be used to activate the lowpower standby mode. Temperature resolution is 1°C. Conversion rate is a nominal8 samples/second. During normal operation, the quiescent current is 200µA(typical). During standby operation, the quiescent current is 5µA (typical). TheTC74 acquires and converts temperature information from its onboard solid-statesensor with a resolution of ±1°C. It stores the data in an internal registerwhich is then read through the serial port.Output temperature as an 8-bit digital wordSimple serial port interface200µA Maximum input/supply current200µA Typical supply currentApplicationsComputers & Computer Peripherals, Automation & Process Control, Power ManagementProduct InformationIC Output Type: DigitalSensing Accuracy Range: ± 3°CSensing Temperature Min: 0°CSensing Temperature Max: +125°CSensor Case Style: TO-220No. of Pins: 5PinsSupply Voltage Min: 2.7VSupply Voltage Max: 5.5VProduct Range: -
