General Description

The MAX6920 is a 12-output, 76V, vacuum fluorescent display (VFD) tube driver that interfaces a multiplexed VFD tube to a VFD controller such as the MAX6850–MAX6853 or to a microcontroller.

The MAX6920 is also ideal for driving either static VFD tubes or telecom relays.

Data is inputted using an industry-standard 4-wire serial interface (CLOCK, DATA, LOAD, BLANK) for compatibility with both industry-standard drivers and Maxim’s VFD controllers.
