IN-1 and IN-2 contain clamping diode to GND.
VAA-VSS, VCC-COM, VB1-VS1 and VB2-VS2 contain internal shunt zener diodes. Note that the
voltage ratings of these can be limited by the clamping current.
For the rising and falling edges of step signal of 10V. VSS=15V to 200V.
According to JESD51-5. JEDEC still air chamber.
