ML9261 Overview
The ML9261/62 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.
