GENERAL DESCRIPTION
The ML9261/62 is a monolithic IC designed for directly driving the grid and anode of the vacuum
fluorescent display (VFD) tube. The device contains a 60-bit shift register, a 60-bit register circuit,
and 60 VFD tube driving circuits on a single chip.
Display data is serially stored in the shift register at the rising edge of a clock pulse.
Setting the
CL
pin low allows all the VFD tube driving circuits to be driven low, which makes it
possible to set the display blanking.
Also, setting both of the
CL
and CHG pins high allows all the VFD tube driving circuits to be
driven high, which provides the easy testing of all lights after final assembly of a VFD tube panel.
