On-state resistance is determined by the lowest voltage of the two (A or B) terminals. switching characteristics over recommended operating free-air temperature range (unless otherwise noted) (see Figure 1) PARAMETER FROM (INPUT) TO (OUTPUT) MIN MAX UNIT tpd¶ A or B B or A 0.35 ns ten OE A or B 2.6 10 ns tdis OE A or B 1 6 ns ¶ The propagation delay is the calculated RC time constant of the typical on-state resistance of the switch and the specified load capacitance, when driven by an ideal voltage source (zero output impedance). |
