FUNCTIONAL DESCRIPTION
Display Data Reset
When the power is turned on, the shift register outputs (PO1 to PO60) and register outputs (O1
to O60) are indeterminate. Consequently the display of a VFD tube may flickers because
unnecessary driver outputs go high. To prevent such flicker, it is required to perform the
following operations.
1. Turn on the logic power supply while the
CL
input is kept low.
2. Set the LS input high.
3. Switch the CLK input from a low level to a high level at least once.
By performing the above operations, the shift register outputs (PO1 to PO60) and register outputs
(O1 to O60) all are set low.
4. Enter display data.
5. Set the
CL
input high.
Data Transfer
Write display data by using a serial transfer.
Serial data is input in the shift register at the rising edge of a CLK input pulse.
When the LS input rises, display data is written in the latch.
Driver Output Control
1. To turn on or off driver outputs by using display data transfered into the shift register, set the
CL
input high and set the CHG input low.
2. To set all the driver outputs low, set the
CL
input low.
3. To set all the driver outputs high, set the
CL
input and CHG input high at a time.
