I'll bite: The datasheet says the HV is controlled by MOSFETs:
"It combines a 20-bit CMOS shift register, data latches and control
circuitry with high-voltage MOSFET outputs".

Interesting. The HV5812 is a CMOS device rated for 80V, so it will be
vulnerable to overstress if the nixie tubes leak (no bleeder resistors are
present).
Has anyone ever had driver failure ? If not, then I guess the blanking time
is sufficient enough for charge to decay to a safe level, or
