Hi,
that makes sense, but I guess you would still run into trouble when
trying to drive ZM1040 at 4.5mA.. I guess the HV9708 is a better choice
in that case.

Since (the way I understand it) the only way appreciable current will
flow is if the HV5812 pin is pulled low, the important specification
is Isink, which is rated at 3.5mA. Remember that we are using the
HV5812 to pull the cathodes to ground to turn on a number.

Adam,
just checked the HV5812 datasheet and it says maximum current is 1mA. Is
that really enough? I mean, most Nixie tubes suck at least 1.5 to 2mA..
