MAX49140 30ns, Low-Power, 3V/5V, Rail-to-Rail Single- Supply Comparator General Description Benefits and Features The MAX49140 is a single high-speed comparator opti- Fast, 30ns Propagation Delay (10mV Overdrive) mized for systems powered from a 3V or 5V supply. The Low-Power 100A Supply Current (V = 3V) DD MAX49140 combines high speed, low power, and rail-to- Optimized for 3V and 5V Applications rail inputs. Propagation delay is 30ns, while supply current Rail-to-Rail Input Voltage Range is only 100A (typ). Low, 500V Offset Voltage Internal Hysteresis for Clean Switching The input common-mode range of the device extends up Output Swing 300mV of Power Rails to both power-supply rails. The output pulls to within 0.3V CMOS/TTL-Compatible Outputs of either supply rail without external pullup circuitry, mak- Small SC70 Package ing the device ideal for interfacing with both CMOS and AEC-Q100 Qualified TTL logic. All input and output pins can tolerate a con- tinuous short-circuit fault condition to either rail. Internal Ordering Information appears at end of data sheet. hysteresis ensures clean output switching, even with slow- moving input signals. The MAX49140 is offered in tiny, 5-pin SC70 package and is fully specified over -40C to +125C automotive temper- ature range. The device is AEC-Q100 qualified.
