Octal bus switch

[1]

[2]

[3]

Measured by the voltage drop between the An and the Bn terminals at the indicated current through the switch. ON resistance is

determined by the lowest voltage of the two (An or Bn) terminals.

10. Dynamic characteristics

[1]

The propagation delay is the calculated RC time constant of the typical ON resistance of the switch and the specified load capacitance,

when driven by an ideal voltage source (zero output impedance).
