LED DISPLAY DRIVER

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.

• 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
