TS339IYDT

Overview

The TS339IYDT is a micropower quad CMOS voltage comparator manufactured by STMicroelectronics. It features an extremely low supply current of 25 µA maximum and operates within a wide single supply range of 2.7 V to 16 V, or dual supplies from ±1.35 V to ±8 V. The device provides four independent comparators in a 14-SOIC package with open-drain outputs capable of sinking up to 20 mA. It exhibits high input impedance with typical input bias and offset currents of 1 pA. The component is qualified for automotive applications under AEC-Q100 standards and supports operation across an extended temperature range of -40°C to +125°C.
