MAX6922/MAX6932/  
MAX6933/MAX6934  
27-, 28-, and 32-Output, 76V,  
Serial-Interfaced VFD Tube Drivers  
General Description  
Features  
The MAX6922/MAX6932/MAX6933/MAX6934 multi-out-  
put, 76V, vacuum-fluorescent display (VFD) tube driv-  
ers 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.  
● 5MHz Industry-Standard 4-Wire Serial Interface  
● 3V to 5.5V Logic Supply Range  
● 8V to 76V Grid/Anode Supply Range  
● -11V to 0V Filament Bias Supply  
(MAX6932/MAX6933/MAX6934 Only)  
● Push-Pull CMOS High-Voltage Outputs  
Data is input using standard 4-wire serial interface  
(CLOCK, DATA, LOAD, BLANK) compatible with other  
VFD drivers and controllers.  
● Outputs can Source 40mA, Sink 4mA Continuously  
● Outputs can Source 75mA Repetitive Pulses  
● Outputs can Be Paralleled for Higher Current Drive  
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.  
● Any Output can Be Used as a Grid or an Anode  
Driver  
● BLANK Input Simplifies PWM Intensity Control  
● -40°C to +125°C Temperature Range as Standard  
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.  
Ordering Information  
PART  
TEMP RANGE  
PIN-PACKAGE  
The MAX6932/MAX6933/MAX6934 have a negative sup-  
ply voltage input, V , allowing the drivers’ output swing  
to be made bipolar to simplify filament biasing in many  
applications.

MAX6932 and MAX6933 are available in 36-pin SSOP  
packages, and the MAX6934 is available in 44-pin PLCC  
and TQFN packages.  
*EP = Exposed pad.  
Maxim also offers a 12-output VFD driver (MAX6920) and  
20-output VFD drivers (MAX6921/MAX6931).
