On-state resistance is determined by the lower of the voltages 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 0.35 0.25 ns ten OE A or B 6.1 1.2 5.6 ns tdis OE A or B 7.5 3.9 7.7 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). |
