Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: Signals on S, D, or IN exceeding V+ or V– will be clamped by
internal diodes. Limit forward diode current to maximum current rating.

Note 3: In-circuit ESD on the switch pins (S or D) exceeds 4kV (see test
circuit).
Note 4: Leakage current with a 5V supply is guaranteed by correlation with
the ±15V leakage current.
