Notes:
1. For max. or min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device type.
2. VDD = 3.0 - 5.5V, TA = 25°C ambient.
3. Measured by the voltage drop between Y+/Y- and the lower of M+/M- and D+/D- at indicated current through the Switch.
4. When the voltage at Y+/Y- is greater than VDD + 0.2V, over-voltage protection limits the output voltage at M+/- and D+/- to protect connected devices from
damage.

Notes:
1. For max. or min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device type.
2. Typical values are at VDD = 3.3V, TA = 25°C ambient.
3. This parameter is determined by device characterization but is not production tested.
4. Time duration for output voltage higher than VOVP when input is connected to 5V.
5. Output voltage observed at M+/M- and D+/D- during over-voltage condition.
6. Tested using a 750 kHz square wave with tr = 75 ns and tf = 75 ns.

Notes:
1. For max. or min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device type.
2. Guaranteed by design.
3. The switch contributes no propagation delay other than the RC delay of the On-Resistance of the switch and the load capacitance. The time constant for the
switch alone is of the order of 0.25ns for 10pF load. Since this time constant is much smaller than the rise/fall times of typical driving signals, it adds very little
propagation delay to the system. Propagation delay of the switch when used in a system is determined by the driving circuit on the driving side of the switch and
its interactions with the load on the driven side.
