MAX6921 Product details

Description

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 telecom relays.
