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.

FEATURES
• Logic supply voltage : 5V
• Driver supply voltage : 65V
• Driver output current IOH : –40 mA
                                    IOL : 1 mA
• Can be directly connected to VF display tube without pull-down resistor
• Built-in 4- to 16-line decoder
• Brightness can be adjusted by DUTY pin
• Package
    24-pin plastic SOP (SOP24-P-430-1.27-K) (Product name: MSC7166GS-K)
