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 compatibili-
ty 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.
Display intensity may also be controlled by pulse-width
modulating the BLANK input.
The MAX6920 has a serial interface data output pin,
DOUT, allowing any number of devices to be cascaded
on the same serial interface.
The MAX6920 is available in a 20-pin SO package.
Maxim also offers VFD drivers with either 20
(MAX6921/MAX6931) or 32 outputs (MAX6922 and
MAX6932).
