MAX9140/MAX9141/ MAX9142/MAX9144 40ns, Low-Power, 3V/5V, Rail-to-Rail Single-Supply Comparators The MAX9140/MAX9141 are single and the MAX9142/ MAX9144 are dual/quad high-speed comparators optimized for systems powered from a 3V or 5V supply. The MAX9141 features latch enable and device shutdown. These devices combine high speed, low power, and railto-rail inputs. Propagation delay is 40ns, while supply current is only 150uA per comparator. The input common-mode range of the MAX9140/ MAX9141/MAX9142/MAX9144 extends beyond both power-supply rails. The outputs pull to within 0.3V of either supply rail without external pullup circuitry, making these devices ideal for interface with both CMOS and TTL logic. All input and output pins can tolerate a continuous short-circuit fault condition to either rail. Internal hysteresis ensures clean output switching, even with slowmoving input signals. The MAX9140/MAX9141/MAX9142/MAX9144 are higherspeed, lower-power, and lower-cost upgrades to industrystandard comparators MAX941/MAX942/MAX944. The MAX9140 are offered in tiny 5-pin SC70 and SOT23 packages. The MAX9141 and MAX9142 are available in 8-pin SOT23 and SO packages, while the MAX9144 is available in both 14-pin SO and TSSOP packages. ●● Line Receivers ●● Battery-Powered Systems ●● Threshold Detectors/Discriminators ●● 3V/5V Systems ●● Zero-Crossing Detectors ●● Sampling Circuits Pin Configurations ●● Fast, 40ns Propagation Delay 10mV Overdrive ●● Low Power • 150uA Supply Current Per Comparator 3V ●● Optimized for 3V and 5V Applications ●● Rail-to-Rail Input Voltage Range ●● Low, 500uV Offset Voltage ●● Internal Hysteresis for Clean Switching ●● Outputs Swing 300mV of Power Rails ●● CMOS/TTL-Compatible Outputs ●● Output Latch MAX9141 Only ●● Shutdown Function MAX9141 Only ●● Available in SC70 and SOT23 Packages Ordering Information PART* PIN-PACKAGE TOP MARK MAX9140AAUK+T 5 SOT23 +AFEJ MAX9140AAXK+T 5 SC70 +ASW MAX9140AAXK/V+T 5 SC70 +AUG MAX9140EXK-T 5 SC70 MAX9140EUK-T 5 SOT23 ADQP MAX9141EKA-T 8 SOT23 AAFD MAX9141ESA MAX9142EKA-T 8 SOT23 AAFE MAX9142ESA MAX9144EUD 14 TSSOP MAX9144ESD 14 SO Note All E-grade devices are specified over the -40°C to +85°C operating temperature range.
