GM6486 Datasheet | SK Hynix

Description The GM6486 is a monolithic MOS integrated circuit produced with high voltage CMOS technology. It is available in a 40-pin dual in-line plastic package. A sin-gle pin controls the LED display brightness by setting a reference current through a variable resistor connect-ed to VDD or to a separated supply of 13.2V maximum.
