Description
STV7710 is a driver for vacuum fluorescent
display (VFD) designed in the ST proprietary BCD
high voltage technology. Using a 1 bit wide data
bus, it can control 96 high current & high voltage
outputs. The STV7710 is supplied with a
separated 70V power output supply. All command
inputs are CMOS and 3.3V logic levels
compatible.
