ML9272MB - LAPIS SEMICONDUCTOR

Description: The ML9272 is a monolithic IC designed for directly driving the grids and anodes 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
