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. RON vs VS Over Supply Voltage AC ELECTRICAL CHARACTERISTICS 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.
