ELECTRICAL CHARACTERISTICS (continued)

(VCC = +2.7V to +5.5V, VCM = 0V, TA = -40°C to +85°C, unless otherwise noted. Typical values are at TA = +25°C.) (Note 1)

Note 1: The MAX998EUT specifications are 100% tested at TA = +25°C. Limits over the extended temperature range are guaran-

teed by design, not production tested.

Note 2: Inferred from CMRR test. Either input can be driven to the absolute maximum limit without false output inversion, as long as

the other input is within the common-mode voltage range.

Note 3: VOS is defined as the mean of trip points. The trip points are the extremities of the differential input voltage required to make

the comparator output change state (Figure 1).

Note 4: The difference between the upper and lower trip points is equal to the width of the input-referred hysteresis zone (Figure 1).

Note 5: Propagation Delay is guaranteed by design. For low overdrive conditions, VTRIP (Figure 1) is added to the overdrive.

Note 6: Propagation-Delay Skew is the difference between the positive-going and the negative-going propagation delay.

Note 7: For design purposes, the tEN can be as high as 60µs.
