Features (VS = 5V, TA = 25°C Typical values unless otherwise specified) Propagation delay 75 nsec Low supply current 65µA Rail-to-Rail input Open drain and push-pull output Ideal for 2.7V and 5V single supply applications Available in space saving packages 5-pin SOT23 5-pin SC70 LMV7239Q is an automotive grade product that is AECQ grade 1 qualified and is manufactured on an automotive grade flow. Description The LMV7235/LMV7239/LMV7239Q are ultra low power, low voltage, 75 nsec comparators. They are guaranteed to operate over the full supply voltage range of 2.7V to 5.5V. These devices achieve a 75 nsec propagation delay while consuming only 65µA of supply current at 5V. The LMV7235/LMV7239/LMV7239Q have a greater than rail-to-rail common mode voltage range. The input common mode voltage range extends 200mV below ground and 200mV above supply, allowing both ground and supply sensing. The LMV7235 features an open drain output. By connecting an external resistor, the output of the comparator can be used as a level shifter. The LMV7239/LMV7239Q features a push-pull output stage. This feature allows operation without the need of an external pull-up resistor. The LMV7235/LMV7239/LMV7239Q are available in the 5-Pin SC70 and 5-Pin SOT23 packages, which are ideal for systems where small size and low power is critical. Applications Portable and battery powered systems Scanners Set top boxes High speed differential line receiver Window comparators Zero-crossing detectors High speed sampling circuits Automotive

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
