Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
intended to be functional, but do not guarantee specific performance limits. For guaranteed specifications and conditions, see the Electrical Characteristics.
Note 2: All pins will survive an ESD impulse of ±2000V using the human body model of 100 pF discharged through a 1.5 k
Ω resistor. In addition, input pins VIN and
the ON/OFF input will withstand ten pulses of ±12 kV from a 150 pF capacitor discharged through a 560
Ω resistor with each pin bypassed with a 22 nF, 100V ca-
pacitor.
