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.
