VFD Supply Voltage
Serial-Data Output. Data is clocked out of the internal shift register to DOUT
on CLK’s falling edge. For the MAX6933 only—VFD anode and grid driver.

No Connection. Not internally connected.
For the MAX6922—No Connection. Not internally connected. For the
MAX6934—bias supply voltage.
Bias Supply Voltage
Blanking Input. High forces outputs OUT_ low without altering the contents
of the output latches. Low enables outputs OUT_ to follow the state of the
output latches.
Ground
Serial-Clock Input. Data is loaded into the internal shift register on CLK’s
rising edge. On CLK’s falling edge, data is clocked out of DOUT.
Load Input. Data is loaded transparently from the internal shift register to the
output latch while LOAD is high. Data is latched into the output latch on
LOAD's rising edge, and retained while LOAD is low.
Serial-Data Input. Data is loaded into the internal shift register on CLK’s
rising edge.
Logic Supply Voltage
Exposed Paddle. Connect to a large ground plane to maximize thermal
performance.
