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.
