Notes: 1. Absolute maximum ratings are those values beyond which the device could be permanently damaged.

Absolute maximum ratings are stress ratings only and functional device operation is not implied.

2. The input and output voltage ratings may be exceeded if the input and output current ratings are

observed.

Note: With supply voltages at or near 2V, the analog switch on-state resistance becomes very nonlinear.

Only digital signals should be transmitted at these low supply voltages.
