SEG1 to 37
Type
O
Decription
Output pins for segment signals for driving VF display tube.
GRID1 to 3
O
Output pins for grid signals for driving VF display tube.
The GRID3 output is not used when the universal VF display tube is used.
When at a "L" level, this pin selects 1/3-duty VF display tube.
When at a "H" level (or when used in the open state), this pin selects universal
VF display tube.
Pin for series data input from microprocessor.
Data is input to the shift register on the rising edge of the CLOCK signal.
Serial clock input pin.
Data is input through the DATA-IN pin at the rising edge of the serial clock.

LGND
RC oscillator connecting pins.
Connect a resistor between the OSC1 and OSC0 pins and a capacitor between
the OSC0 pin and the ground.
Chip select input pin. Circuit operation is valid when this pin is at a "L" level.
Power supply pins. When using these pins, connect each of them to the power
supply.
Ground pins for driver and logic. These pins can be connected with each other
when they are used.
