MAX6920 Overview
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.
