    General Description

    The LMH7322 is a dual comparator with 700 ps propagation delay, low dispersion of 75 ps and an input voltage range that extends from VCC-1.5V to VEE. The devices can be operated from a wide supply voltage range of 2.7V to 12V. The adjustable hysteresis adds flexibility and prevents oscillations. Both the outputs and latch inputs of the LMH7322 are RSPECL compatible. When used in combination with a VCCO supply voltage of 2.5V the outputs have LVDS compatible levels.

    The LMH7322 is available in a 24-pin LLP package.

    Reliability Metrics

    Part Number Process EFR Reject EFR Sample Size PPM LTA Rejects LTA Device Hours FITS MTTF (Hours)
    LMH7322SQVIP 100128010011550004327734403
    LMH7322SQEVIP 100128010011550004327734403
    LMH7322SQXVIP 100128010011550004327734403

    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.
