Vacuum Fluorescent
Display Tube Driver
The VFD Driver is a microprocessor interface IC that drives a
multiplexed VF (Vacuum Fluorescent) display tube. It consists of a
34–bit shift register, a 34–bit transparent data latch, a metal mask
ROM, six 20 mA anode output drivers, twenty–five 2 mA anode
output drivers, and three 50 mA grid drivers with output enables. The
metal mask programmable ROM (at factory request) allows the 31
anode outputs and 3 grid outputs to be assigned to any of the 34 serial
data bits.
