42-Bit Vacuum Fluorescent Display Tube Driver with Digital Dimming Function
GENERAL DESCRIPTION
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.
FEATURES
Power supply voltage: 8V to 18V (Built-in 5V regulator for logic)
Operating temperature range: –40 to +105
