MSC7166

16-Bit Grid Driver with 4 to 16-Decoder

GENERAL DESCRIPTION

The MSC7166 is a driver IC designed to directly drive the grids of a vacuum fluorescent display

tube.

Since this IC has a built-in 4 to 16-line decoder and 16 output circuits, a signal device of MSC7166

can replace a set of the following three: two devices of either MSL912 or MSL918 and one device

of either MSM4514 or MSM74HC4514.

Setting the DUTY pin to the "L" level makes all driver outputs go "L". Blanking can be set using

this function.
