CS1087
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
32–bit shift register, a 32–bit transparent data latch, a metal mask
ROM, six 20 mA anode output drivers, twenty–three 2 mA anode
output drivers, and three 50 mA grid drivers with output enables.
