ML9261/6260-Bit Vacuum Fluorescent Display Tube Grid / Anode Driver

The ML9261 / ML9262 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.
