[2] this is the increase in supply current for each input th at is at the specified ttl voltage level rather than v cc or gnd. [3] measured by the voltage drop between the na and the nb termi nals at the indicated current through the switch. on resistance is determined by the lowest voltage of the two (na, nb) terminals. 11. dynamic characteristics [1] the propagation delay is the calculated rc ti me constant of the typical on resistanc e of the switch and the specified load c apacitance, when driven by an ideal volt age source (zero output impedance).
