The MM5450 and MM5451 LED display drivers are monolithic MOS IC’s fabricated in an N-Channel,metal-gate process. The technology produces low-threshold, enhancement-mode, and ion-implanted depletion-mode devices.A single pin controls the LED display brightness setting a reference current through a variable resistor connected to the supply.
