20-Output, 76V, Serial-Interfaced VFD Tube Drivers

General Description The MAX6921/MAX6931 are 20-output, 76V, vacuum fluorescent display (VFD) tube drivers that interface a multiplexed VFD tube to a VFD controller, such as the MAX6850–MAX6853, or to a microcontroller. The MAX6921/MAX6931 are also ideal for driving static VFD tubes or telecom rel
