Propagation delay is 720 ns maximum — fast enough for most power-supply sequencing and fault-detection loops, but not for high-speed switching regulators or GHz-class signal recovery. The 79 dB CMRR gives reasonable rejection of common-mode noise on a long sensor cable, though a precision comparator with higher CMRR would be chosen for millivolt-level thresholds. Quiescent current sits at 26 µA maximum, so the part suits always-on sensing in battery-powered nodes without draining the rail. Input offset voltage is 5 mV max at 5 V — acceptable for threshold detection where the trip point has several millivolts of hysteresis margin. The 8-SOIC footprint is a common industry layout; no board respin needed if you are replacing a generic dual comparator in the same land pattern.","metaTitle":"STMicroelectronics TS332IDT General Purpose Comparator","metaDescription":"ST TS332IDT dual rail-to-rail comparator with open-drain outputs, 720 ns propagation delay, 1.6 V to 5 V supply, -40°C to 125°C range.
