MM5450/51  
LED Display Driver  
Features  
General Description  
• Continuous Brightness Control  
• Serial Data Input  
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.  
• No Load Signal Requirement  
• Enable (MM5450 Only)  
• Wide Power Supply Operation  
• TTL Compatibility  
A single pin controls the LED display brightness by  
setting a reference current through a variable resistor  
connected to the supply.  
• 34 or 35 Outputs, 15 mA Capability  
• Alphanumeric Capability  
Applications  
• Industrial Control Indicator  
• Relay Driver  
• Digital Clock, Thermometer, Counter, Voltmeter  
• Instrumentation Readouts
