MSC1162A
40-Bit Vacuum Fluorescent Display Tube Grid/Anode Driver
GENERAL DESCRIPTION
The MSC1162A 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.
