Detailed Description
The MAX6922/MAX6932/MAX6933/MAX6934 are VFD
tube drivers comprising a 4-wire serial interface driving
high-voltage Rail-to-Rail ? output ports. The driver is suit-
able for both static and multiplexed displays.
The output ports feature high current-sourcing capabili-
ty to drive current into grids and anodes of static or
multiplex VFDs. The ports also have active current sink-
ing for fast discharge of capacitive display electrodes
in multiplexing applications.
Rail-to-Rail is a registered trademark of Nippon Motorola, Ltd.
Figure 3. MAX6932/MAX6933/MAX6934 CMOS Output Driver
Structure
The 4-wire serial interface comprises a shift register
and transparent latch with 32 bits for the MAX6922/
MAX6934, 28 bits for the MAX6933, and 27 bits for the
MAX6932. The shift register is written through a clock
input CLK and a data input DIN. For the MAX6922/
MAX6932/MAX6934, the data propagates to a data out-
put DOUT. The data output allows multiple drivers to be
cascaded and operated together. The output latch is
transparent to the shift register outputs when LOAD is
high, and latches the current state on the falling edge
of LOAD.
