(1) Electrical Table values apply only for factory testing conditions at the temperature indicated. Factory testing conditions result in very
limited self-heating of the device such that T_J = T_A. No specification of parametric performance is indicated in the electrical tables under
conditions of internal self heating where T_J > T_A.
(2) All limits are specified by testing or statistical analysis.
(3) Typical values represent the most likely parametric norm as determined at the time of characterization. Actual typical values may vary
over time and will also depend on the application and configuration. The typical values are not tested and are not guaranteed on
shipped production material.
(4) Propagation Delay Skew, Δt_PD, is defined as the average of Δt_PDLH and Δt_PDHL.
(5) The rise or fall time is the average of the Q and Q rise or fall time.
