NOTES:
10. Note about I
12. Total Power dissipation per comparator can be approximately calculated from the following:
13. Compliance to datasheet limits is assured by one or more methods: production test, characterization and/or design.
11. Limits should be considered typical and are not production tested.

9. Lab characterization, room temperature, timing parameters matched stimulus/loads, channel-to-channel skew < 500ps, 1ns maximum by design
P = (V
Because the ISL55142 has two comparators, the power dissipation would be twice of P calculated from this equation. The ISL55143 would be
four times P.

Although there is no electrical difference between the CV
and CV
threshold and CV
easier to understand the utilization of a dual threshold
comparator. Essentially this enables the qualification of an
incoming signal into three states. In Figure 2, the three
states are Valid Low <0.4V, No-man’s-land (between 0.4
and 2.4V), Valid High >2.4V. Table 2 shows how the Q
truth table would be utilized in the real world.
