MSC7166

E2C0032-27-Y2 ¡ Semiconductor ¡ Semiconductor MSC7166 16-Bit Grid Driver with 4 to 16-Decoder This version: Nov. 1997 MSC7166 Previous version: Jul. 1996 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) 1/8 ¡ Semiconductor MSC7166 BLOCK DIAGRAM V DISP(+) V DD S 1 S 2 S 3 SEL0 S 4 S 5 SEL1 SEL2 4 to 16 DECODER SEL3 S10 S11 S12 S13 S14 S15 S16 DUTY V SS S 8 S 9 S 6 S 7 GRID 1 GRID 2 GRID 3 GRID 4 GRID 5 GRID 6 GRID 7 GRID 8 GRID 9 GRID10 GRID11 GRID12 GRID13 GRID14 GRID15 GRID16 2/8 ¡ Semiconductor MSC7166 INPUT AND OUTPUT CONFIGURATION Schematic Diagram of Logic Input Circuit VDD VDD Input VSS VSS VSS Schematic Diagram of Driver Output Citcuit VDISP(+) VDISP(+) Output VSS VSS 3/8 ¡ Semiconductor MSC7166 PIN ...
