It pulls a maximum 250 µA quiescent across its full supply range, which spans 1.1 V to 40 V single supply or ±0.55 V to ±20 V dual supplies. That wide operating window makes it a natural fit for battery-monitoring circuits, over-voltage/under-voltage lockout, and industrial control inputs where the rail can vary. The open-collector outputs with internal pull-up resistors simplify interfacing to logic families or driving a small load directly — each output can sink 70 mA at 4.5 V. ## 6 µs propagation delay — what it means on the bench A 6 µs max propagation delay places this comparator in the slow-but-predictable category. It will not catch a fast-switching PWM edge or a sub-microsecond glitch, but it is more than adequate for power-good flags, temperature hysteresis loops, and pushbutton debounce. The 115 dB CMRR and 110 dB PSRR keep the trip point stable when the supply or common-mode voltage shifts — useful when the comparator shares a noisy rail with a switching regulator. ## Temperature grade and board environment Rated 0°C to 70°C, this is a commercial-temperature part. It belongs in office equipment, appliance control boards, and indoor instrumentation. If the board lives in a motor-drive cabinet, a telecom outdoor cabinet, or an engine bay, step to the industrial-grade LT1018IS8#TRPBF (-40°C to 85°C) — same pinout, same 16-SO wide-body footprint, same electrical specs.","metaTitle":"LT1018CSW#PBF Micropower Dual Comparator, 6 µs, 16-SOIC","metaDescription":"LT1018CSW#PBF dual comparator from Analog Devices. 1.1 V to 40 V supply, 6 µs max propagation delay, 250 µA quiescent.
