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 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)
