Notes:
1. "Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the device at these or any
other conditions beyond those indicated in the operational sections of this specification is not implied.
2. The input and output negative voltage ratings may be exceeded if the input and output diode current ratings are observed.
3. Control input must be held HIGH or LOW; it must not float.

2. Typical values are at VDD = 1.8V, TA = 25°C ambient and maximum loading.
3. For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device type.
4. Measured by the voltage drop between A and Y pin at indicated current through the switch. On-Resistance is determined by the lower of the
voltages on the two (I,Y) pins.
