VFD Anode and Grid Drivers. OUT4 to OUT0 are push-pull outputs swinging from
V BB to GND (MAX6921 only), and from V BB to V SS (MAX6931 only).
Serial-Data Input. Data is loaded into the internal shift register on CLK’s rising edge.
Logic Supply Voltage. Bypass to GND with 100nF capacitor.
VFD Tube Supply Voltage. Bypass to GND with 100nF capacitor.
Serial-Clock Output. Data is clocked out of the internal shift register to DOUT on
CLK’s rising edge.
