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) VCC = 4 V VCC = 5 V ± 0.5 V UNIT (INPUT) (OUTPUT) MIN MAX MIN MAX tpd¶ A or B B or A 1.25 1.25 ns ten OE A or B 3.1 9 2.7 8.6 ns tdis OE A or B 2.7 6.3 2.3 6.9 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). |
