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.

Features

• Power On Reset

• Display Dimming Possible

• Three, 50 mA Grid Drivers

• Anodes:

– 6 @ 20 mA

– 23 @ 2 mA
