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.
FEATURES
• Logic supply voltage : 5V
• Driver supply voltage : 65V
• Driver output current I
• 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)
