[2] this is the increase in supply current for each input that is at the speci?ed ttl voltage level rather than v cc or gnd. [3] measured by the voltage drop between the a and the b terminals at the indicated current through the switch. on resistance is determined by the lowest voltage of the two (a or b) terminals. 10. dynamic characteristics [1] this parameter is warranted but not production tested. the propagation delay is based on the rc time constant of the typical on resistance of the switch and a load capacitance, when driven by an ideal voltage source (zero output impedance).
