MAX6921 Overview
The MAX6921/MAX6931 are 20-output, 76V, vacuumfluorescent 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 tele relays. Data is input using an industry standard 4-wire serial interface (CLOCK, DATA, LOAD, BLANK), patibile with either Maxim’s or...
