The STMicroelectronics TS883 is a rail-to-rail 0.9V Nano power, open drain dual comparators. It features an ultra low supply current of 250 nA typical per operator with rail-to-rail input capability and open-drain output. Can be used in a wide range of portable applications which is possible due to the performance of these comparator. This series of comparator can be used over a wide temperature range of -40 to +125 °C which keeps the current consumption at an ultra low level.

Propagation delay is typically 2 μs
Minimize battery supply leakage
Enhances the battery lifetime
ESD tolerance of about 8 kV HBM
