MM5450MM5451 LED Display Drivers
General Description
The MM5450 and MM5451 are monolithic MOS integrated
circuits utilizing N-channel metal-gate low threshold en-
hancement mode and ion-implanted depletion mode devic-
es They are available in 40-pin molded or cavity dual-in-line
packages The MM5450MM5451 is designed to drive com-
mon anode-separate cathode LED displays A single pin
controls the LED display brightness by setting a reference
current through a variable resistor connected to V
