MAX6920
MAX6920 is Serial-Interfaced VFD Tube Driver manufactured by Maxim Integrated.
12-Output, 76V, Serial-Interfaced VFD Tube Driver
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 tele relays.
Data is inputted using an industry-standard 4-wire serial interface (CLOCK, DATA, LOAD, BLANK) for patibility with both industry-standard drivers and Maxim’s VFD controllers.
For easy display control, the active-high BLANK input forces all driver outputs low, turning the display off, and automatically puts the MAX6920 into shutdown mode....
