SWITCHING CHARACTERISTICS
NOTE:
1. The propagation delay is the calculated RC time constant of the typical on-state resistance of the switch and the specified load capacitance driven by an ideal voltage source
NOTES:
1. Typical values are at V
2. The increase in supply current is attributable to each current that is at the specified voltage level rather than V
3. This is measured by the voltage drop between the A and B terminals at the indicated current through the switch.
