MAX6922 Overview
The MAX6922/MAX6932/MAX6933/MAX6934 multi-output, 76V, vacuum-fluorescent display (VFD) tube drivers that interface a VFD tube to a microcontroller or a VFD controller, such as the MAX6850 MAX6853. The MAX6922/MAX6934 have 32 outputs, while the MAX6932 has 27 outputs, and the MAX6933 has 28 outputs. All devices are also suitable for driving tele relays.
