A Vacuum Fluorescent Display (VFD) tube is a type of display technology that uses a vacuum to generate visible light through the process of fluorescence. It consists of a glass envelope containing a vacuum, multiple cathodes (emitters), and anodes (segments or grids) made of phosphor-coated material. When voltage is applied between a cathode and an anode, electrons are emitted from the cathode and strike the phosphor-coated surface of the anode, causing it to emit visible light.
The grid/anode driver circuit in a VFD serves the purpose of controlling which segments or grids of the display are illuminated at any given time. It plays a crucial role in displaying alphanumeric characters, symbols, and other information on the VFD.
The Part Number is C1162.
The function of this IC is 40-Bit Vacuum Fluorescent Display Tube Grid/Anode Driver.
The Package is TSSOP 60 Pin Type
Manufacturer: Oki Semiconductor
The C1162 is a monolithic IC designed for directly driving the grid and anode of the vacuum
fluorescent display tube. The device contains a 40-bit bidirectional shift register, a 40-bit latch
circuit, and 40-output circuit 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 driver outputs 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 driver outputs to be driven high, which provides the easy testing of all lights after final assembly of a VFD tube panel.
The MSC1162A is compatible with the MSC1162.
