For a window comparator or a simple over-temperature latch, that saves two components and a short PCB trace. ## 10 µA quiescent — battery-budget friendly At 10 µA maximum quiescent current, this comparator adds negligible drain to a battery-powered sensor node. Paired with the 5 pA input bias current, it can monitor a high-impedance source like a thermistor or a photodiode without loading the signal. ## 78 dB CMRR and PSRR — rejection of common-mode and supply noise With 78 dB common-mode rejection ratio and 78 dB power-supply rejection ratio, the threshold stays accurate even when the input common-mode voltage shifts or the supply has ripple. This matters in a motor-drive environment where the ground bounces and the 5 V rail carries switching noise.","metaTitle":"TLV7021DCKT comparator, 350 ns propagation delay","metaDescription":"TLV7021DCKT single comparator with 4.2 mV hysteresis, 10 µA quiescent current, 1.6 V to 5.5 V supply, -40°C to 125°C range.
