General Description
MC74 General Description
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 8bit serial digital word. Communication with the MC74 is accomplished via 2wire SMBus/I2Ccompatible serial port. Temperature resolution is 1. Conversion rate is a nominal 8 samples/sec. Power consumption is only 200 A (5 A Standby).
