With the daughterboard installed in the ZIF socket in the negative position (silkscreen
arrows pointing same direction, daughterboard is as far as possible from the ZIF lever),
and AMP1 set to -1.5 kV and AMP2 set to +5V, these waveforms were obtained:
Top = Logic output for 0V input
Bottom = high voltage pulse
Top = Logic output for 5V input
Bottom = high voltage pulse
These results show that the HCPL-7721 has a much lower CMTI tolerance than the
VO3120.
The actual daughterboard and DUT are shown below, configured for a 5V logic input:
