MC74 数据手册

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 µA Standby).
