LED DISPLAY DRIVER

The MM5450 LED display drivers are monolithic MOS IC’s fabricated in an N-Channel, metalgate 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
