4-bit bus switch
10. Dynamic characteristics
[1] All typical values are measured at T
amb
=25C and at nominal V
CC
.
[2] The propagation delay is the calculated RC time constant of the typical on-state resistance of the switch and the load capacitance, when
driven by an ideal voltage source (zero output impedance).
