MM5451

MM5450/5451 MM5450/5451 LED Display Driver Micrel General Description Features 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. Applications 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 Industrial control indicator Relay driver Digital clock, thermometer, counter, voltmeter Instrumentation readouts Ordering Information Part Number MM5450BN MM5451BN MM5450BV MM5451BV Junction Temp.
