I need to drive a single IV12 vacuum fluorescent display from a BCD to 7 segment chip. I could use level shifters like the CD40109B or CD4504B but they don't have 7 devices in one chip (4 and 6) and only drive 18 volts which might work. I could use a ULN2803 transistor array with 7 pullup resistors on the outputs. The problem is the BCD to 7 decoders (e.g. CD4511) are usually active high, which I need, but the ULN2803 is an inverter which I don't need. A CD4543B might work as the BCD to 7 and can be selected for inverted outputs but it is designed for LCDs not driving transistors. The 74LS47 has the right polarity to drive the transistor array but it has open collector outputs so 7 more resistors are required. Any suggestions that don't get even more complicated (shift registers, octal inverters, arduinos, etc) I'm looking for a convenient driver chip.
