... Specified propagation delay dispersion performance is only achieved by keeping parasitic capacitive loads at or below the specified minimums. The outputs of the ADCMP604 and ADCMP605 are designed to directly drive any standard LVDS- compatible input. USING/DISABLING THE LATCH FEATURE The latch input is designed for maximum versatility. It can safely be left floating or it can be driven low by any standard TTL/CMOS device as a high speed latch ...

... The ADCMP604 and ADCMP605 dispersion is typically < 1 the overdrive varies from 125 mV. This specification applies to both positive and negative signals because each the ADCMP604 and ADCMP605 have substantially equal delays for positive-going and negative-going inputs and very low output skews. ...
