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 = 2.5 V ± 0.2 V VCC = 3.3 V ± 0.3 V UNIT PARAMETER (INPUT) (OUTPUT) MIN MAX MIN MAX UNIT tpd¶ A or B B or A 0.15 0.25 ns ten OE A or B 2 4.6 2 4.4 ns tdis OE A or B 1.1 3.9 1 4.2 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). |
