Serial-Interfaced VFD Tube Drivers
General Description
Features
The MAX6922/MAX6932/MAX6933/MAX6934 multi-out-
put, 76V, vacuum-fluorescent display (VFD) tube drivers
that interface a VFD tube to a microcontroller or a VFD
controller, such as the MAX6850 –MAX6853. The
MAX6922/MAX6934 have 32 outputs, while the MAX6932
has 27 outputs, and the MAX6933 has 28 outputs. All
devices are also suitable for driving telecom relays.
Data is input using standard 4-wire serial interface
(CLOCK, DATA, LOAD, BLANK) compatible with other
VFD drivers and controllers.
For easy display control, the active-high BLANK input
forces all driver outputs low, turning the display off, and
automatically puts the IC into shutdown mode. Display
intensity may also be controlled by directly pulse-width
modulating the BLANK input.
The MAX6922/MAX6932/MAX6934 have a serial inter-
face data output, DOUT, allowing any number of
devices to be cascaded on the same serial interface.
