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
resistor. In addition, input pins V
IN
and
the ON/OFF input will withstand ten pulses of
±
12 kV from a 150 pF capacitor discharged through a 560
resistor with each pin bypassed with a 22 nF, 100V ca-
pacitor.
