The MAX9140/MAX9141 are single and the MAX9142/MAX9144 are dual/quad high-speed comparators opTImizedfor systems powered from a 3V or 5V supply. TheMAX9141 features latch enable and device shutdown.These devices combine high speed, low power, andrail-to-rail inputs. PropagaTIon delay is 40ns, while supplycurrent is only 150μA per comparator.The input common-mode range of the MAX9140/MAX9141/MAX9142/MAX9144 extends beyond bothpower-supply rails. The outputs pull to within 0.3V ofeither supply rail without external pullup circuitry, makingthese devices ideal for interface with both CMOSand TTL logic. All input and output pins can tolerate aconTInuous short-circuit fault condiTIon to either rail.Internal hysteresis ensures clean output switching, evenwith slow-moving input signals.The MAX9140/MAX9141/MAX9142/MAX9144 are higher-speed, lower-power, and lower-cost upgrades toindustry-standard comparators MAX941/MAX942/MAX944.The MAX9140 are offered in tiny 5-pin SC70 and SOT23packages. The MAX9141 and MAX9142 are available in8-pin SOT23 and SO packages, while the MAX9144 isavailable in both 14-pin SO and TSSOP packages.ApplicationsLine ReceiversBattery-Powered SystemsThreshold Detectors/Discriminators3V/5V SystemsZero-Crossing DetectorsSampling Circuits
