NOTES:
9. Lab characterization, room temperature, timing parameters matched stimulus/loads, channel-to-channel skew < 500ps, 1ns maximum by design
10. Note about ICC measurement input can approach 140mA (single comparator) at maximum pattern rates
11. Limits should be considered typical and are not production tested.
12. Total Power dissipation per comparator can be approximately calculated from the following:
P = (VCC-VEE)*8.25mW + 90pF*(VCC-VEE)^2*f + CL*(VCC-VEE)^2*f, where f is the operating frequency and CL is the load capacitance.
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.
13. Compliance to datasheet limits is assured by one or more methods: production test, characterization and/or design.

Although there is no electrical difference between the CVA
and CVB Inputs, if one defines CVA as being the high
threshold and CVB being the low threshold, it becomes
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
