42-Bit Vacuum Fluorescent Display Tube Driver With Digital Dimming Function

The MSC1209 is a Bi-CMOS Display driver for a 1/2-duty Vacuum Fluorescent Display tube. The MSC1209 consists of an 84-bit Shift register an 84-bit latch circuit, a 10-bit digital dimming circuit, 42-bit segment drivers, a 2-bit grid circuit, and a cascade control circuit. The MSC1209 is interfaced with a Microcontroller by using three signal lines of LOAD, Clock and DATA. The cascaded MSC1209 ICs CAN share LOAD, Clock and DATA.
