Description
The AT30TS74 is a complete, precise temperature monitoring device designed for use in a variety of applications which require the measuring of local temperatures as an integral part of the systems function and/or reliability. The AT30TS74 device combines a high-precision digital temperature sensor, programmable high and low temperature alarms, and a 2-Wire I2C and SMBus (System Management Bus) compatible serial interface into a single compact package.
