UDN6118A VFD driver IC

I haven't tried it myself yet, but the (obsolete, discontinued) UDN6118A IC is an 8-line driver specifically designed for driving vacuum fluorescent displays. With two chips of these, up to 8x "7-segment + decimal-point" displays can be controlled through multiplexing.

Apparently UDN6128A and XO-951 are suitable replacements.

These IC's don't seem to be cheap either, but they do simplify wiring.
