MAX9140/MAX9141/ 40ns, Low-Power, 3V/5V, Rail-to-Rail MAX9142/MAX9144 Single-Supply Comparators General Description Features Fast, 40ns Propagation Delay (10mV Overdrive) The MAX9140/MAX9141 are single and the MAX9142/ Low Power MAX9144 are dual/quad high-speed comparators optimized 150A Supply Current Per Comparator (3V) for systems powered from a 3V or 5V supply. The MAX9141 Optimized for 3V and 5V Applications features latch enable and device shutdown. These devices Rail-to-Rail Input Voltage Range combine high speed, low power, and rail-to-rail inputs. Low, 500V Offset Voltage Propagation delay is 40ns, while supply current is only Internal Hysteresis for Clean Switching 150A per comparator. Outputs Swing 300mV of Power Rails The input common-mode range of the devices extends beyond CMOS/TTL-Compatible Outputs both power-supply rails. The outputs pull to within 0.3V of Output Latch (MAX9141 Only) either supply rail without external pullup circuitry, making these Shutdown Function (MAX9141 Only) devices ideal for interface with both CMOS and TTL logic. All Available in SC70 and SOT23 Packages input and output pins can tolerate a continuous short-circuit AEC-Q100 Qualified (MAX9140AAXK/V+T Only) fault condition to either rail. Internal hysteresis ensures clean output switching, even with slow-moving input signals. The devices are higher-speed, lower-power, and lower- cost upgrades to industry-standard 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.
