Devices are 100% production tested at TA = +25°C. All temperature limits are guaranteed by design.

Input Offset Voltage is defined as the center of the input-referred hysteresis zone. Specified for VCM = 0. See Figure 1.

Trip Point is defined as the input voltage required to make the comparator output change state. The difference

between upper (VTRIP+) and lower (VTRIP-) trip points is equal to the width of the input-referred hysteresis zone (VHYST).

Specified for an input common-mode voltage (VCM) of 0. See Figure 1.

Inferred from the CMRR test. Note that a correct logic result is obtained at the output, provided that at least one input is

within the VCMR limits. Note also that either or both inputs can be driven to the upper or lower absolute maximum limit with-

out damage to the part.

Tested over the full-input voltage range (VCMR).

Differential Propagation Delay is specified as the difference between any two channels in the MAX9107/MAX9108 (both

outputs making either a low-to-high or a high-to-low transition).

Propagation Delay Skew is specified as the difference between any single channel’s output low-to-high transition (tPD+)

and high-to-low transition (tPD-).

Latch specifications apply to MAX9109 only. See Figure 2.
