Overview
MC74 Serial Digital Temperature Sensor The MC74 is a serial digital temperature sensor suited for low cost applications.
Temperature data is converted from the integrated thermal sensing element and made available as an 8–bit serial digital word.
Communication with the MC74 is accomplished via 2–wire SMBus/I2C–compatible serial port.
Temperature resolution is 1°C.
Conversion rate is a nominal 8 samples/sec.
Power consumption is only 200 µA (5.
0 µA Standby).
Features • Temperature Range: –40°C to +125°C • Outputs Temperature as an 8–Bit Digital Word • Simple Serial Port Interface • Solid State Temperature Sensing: ±2°C Accuracy from +25°C to +85°C ±3°C Accuracy from 0°C to +125°C • 3.
