Features (VCCI = VCCO = +5V, VEE = 0V.) Propagation delay 700 ps Overdrive dispersion 20 ps Fast rise and fall times 150 ps Supply range 5V to 12V Input common mode range extends 200 mV below negative rail RSPECL outputs Description The LMH7324 is a quad comparator with 700 ps propagation delay and low dispersion of 20 ps for a supply voltage of 5V. The input voltage range extends 200 mV below the negative supply. This enables the LMH7324 to ground sense even when operating on a single power supply. The device operates from a wide supply voltage range from 5V to 12V, which allows for a wide input voltage range. However, if a wide input voltage range is not required, operating from a single-ended 5V supply results in a significant power savings, and less heat dissipation. The outputs of the LMH7324 are RSPECL compatible and can also be configured to create LVDS levels. The LMH7324 operates over the industrial temperature range of −40°C to 125°C. The LMH7324 is available in a 32-Pin LLP package. Applications • Digital receivers • High speed signal restoration • Zero-crossing detectors • High speed sampling • Window comparators • High speed signal triggering

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.
