MM5450/5451  
LED Display Driver  
General Description  
Features  
Continuous brightness control  
Serial data input  
No load signal requirement  
Enable (on MM5450)  
Wide power supply operation  
TTL compatibility  
34 or 35 outputs, 15mA capability  
Alphanumeric capability  
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 by setting  
a reference current through a variable resistor connected  
to the supply.
