HANDLING
Inputs and outputs are protected against electrostatic discharge in normal handling. However, to be totally safe, it is
desirable to take normal precautions appropriate to handling MOS devices.
ESD according to MIL STD 883C - method 3015 (HBM 1500 , 100 pF) 3 pulses positive and 3 pulses negative on each
pin versus ground - Class 1: 0 to 1999 V.
