2 Absolute maximum ratings and operating conditions
Note: Absolute maximum ratings are those values beyond which damage to the device may occur.
Functional operation under these conditions is not implied.

1. For voltage drops across the switch greater than 1.2 V (switch on), excessive V
CC
current may be drawn; i.e., the current
out of the switch may contain both V
CC
and switch input components. The reliability of the device is unaffected unless the
maximum ratings are exceeded.
