MSC7166 16-Bit Grid Driver with 4 to 16-Decoder

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.
