NOTES:

3. Measured by the voltage drop between the A and the B terminals at the indicated current through the switch. On-state resistance is

determined by the lowest voltage of the two (A or B) terminals.

NOTE:

1. This parameter is warranted but not production tested. The propagation delay is based on the RC time constant of the typical on-state

resistance of the switch and a load capacitance of 50 pF, when driven by an ideal voltage source (zero output impedance).
