MM5451 Datasheet | Micrel Semiconductor

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 patibility - 34 or 35 outputs, 15mA capability - Alphanumeric capability - Industrial control indicator - Relay...
