Output Swing 300mV of Power Rails
CMOS/TTL-Compatible Outputs
Small SC70 Package
AEC-Q100 Qualified

The MAX49140 is a single high-speed comparator optimized for systems powered from a 3V or 5V supply. The MAX49140 combines high speed, low power, and rail-to-rail inputs. Propagation delay is 30ns, while supply current is only 100µA (typ).

The input common-mode range of the device extends up to both power-supply rails. The output pulls to within 0.3V of either supply rail without external pullup circuitry, making the device ideal for interfacing 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 slow-moving input signals.

The MAX49140 is offered in tiny, 5-pin SC70 package and is fully specified over -40°C to +125°C automotive temperature range. The device is AEC-Q100 qualified.
