SOT23, 1.8V, Nanopower, Beyond-the-Rails Comparators With/Without Reference ELECTRICAL CHARACTERISTICS—MAX919/MAX920 (continued)
(VCC = +5V, VEE = 0V, VCM = 0V, TA = -40°C to +85°C, unless otherwise noted. Typical values are at TA = +25°C.) (Note 1)

Note 1:
All specifications are 100% tested at TA = +25°C. Specification limits over temperature (TA = TMIN to TMAX) are guaranteed by design, not production tested.
Note 2:
VOS is defined as the center of the hysteresis band at the input.
Note 3:
The hysteresis-related trip points are defined as the edges of the hysteresis band, measured with respect to the center of the band (i.e., VOS) (Figure 2).
Note 4:
Specified with an input overdrive (VOVERDRIVE) of 100mV, and load capacitance of CL = 15pF. VOVERDRIVE is defined above and beyond the offset voltage and hysteresis of the comparator input. For the MAX917/MAX918, reference voltage error should also be added.
