Dual and Window 4ns High-Speed Comparators

VSD is the digital supply voltage from VSD to ground

ISD is the digital supply current per comparator

ISD strongly depends on the input switching frequency.

Please refer to the performance curve to choose the input

driving frequency. Having obtained the power dissipa-

tion, the maximum junction temperature can be

determined as follows:

TJMAX = TMAX + ΘJA × PDISS

of the range set by VREFH and VREFL, the input in range

is low.

If VIN is in the range of VREFL < VIN < VREFH, both out-

puts go high and the input in range is high. If VIN is out
