Accuracy from +25 C to +85 C- 3 C (max.) Accuracy from 0 C to +125 C Supply Voltage of to Low Power:- 200 A (typ.) Operating Current- 5 A (typ.) Standby Mode CurrentApplications Thermal Protection for Hard Disk Drives and other PC Peripherals PC Card Devices for Notebook Computers Low Cost Thermostat Controls Power Supplies Thermistor ReplacementPackage TypesGeneral DescriptionThe TC74 is a serially accessible, digital temperaturesensor particularly suited for low cost and small form-factor applications.
Nov 29, 2012 · TC74 always operates as a Slave. The serial protocol is illustrated in Figure 3-1. All data transfers have two phases and all bytes are transferred MSB first. Accesses are initiated by a START condition, followed by a device address byte and one or more data bytes. The device address byte includes a Read/Write selec-tion bit.
