NOTES ON USE

1. Connect GND1 to GND2 externally to be an equal potential voltage.

2. The contents of the shift register are undefined when the power is applied.

Therefore, unnecessary driver outputs may be driven high just after power-on, and

the VFD tube may flicker.

To avoid this, follow the procedures:

1) Apply the driver power supply after applying the logic power supply, with the

CL pin remained low.

2) Start displaying by setting the CL pin high after in putting display data the shift

register through the DIN pin.
