STMicroelectronics TS331 micropower low-voltage rail-to-rail comparators can operate with a supply voltage ranging from 1.6 to 5V with only 20 µA current consumption. Rail-to-rail inputs make the STMicroelectronics TS331 an ideal choice for low-voltage applications. The TS331 low-voltage comparator features low output saturation voltage and low propagation delay of 210 ns. SOT23-5 and SC70-5 package availability is a real advantage for space-saving constraints. The SC70-5 is approximately half the size of the SOT23-5. The TS331 is specified for a wide temperature range of -40ºC to +125ºC, making it ideal for a wide range of applications.
