(2) This is the increase in supply current for each input that is at the specified voltage level, rather than VCC or GND. (3) Measured by the voltage drop between the A and B terminals at the indicated current through the switch. On-state resistance is determined by the lower of the voltages of the two (A or B) terminals. over recommended operating free-air temperature range (unless otherwise noted) (see Figure 1) VCC = 2.5 V VCC = 3.3 V FROM TO ± 0.2 V ± 0.3 V PARAMETER UNIT (INPUT) (OUTPUT) MIN MAX MIN MAX tpd(1) A or B B or A 0.15 0.25 ns ten OE A or B 1 6 1 4.7 ns tdis OE A or B 1 6.1 1 6.4 ns (1) 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). 4 |
