M5451 LED DISPLAY DRIVERS

-The M5450 and M5451 are monolithic MOS intet(s)grated circuits produced with an N-channel silicon gate technology. They are available in 40-pin dual cin-line plastic packages. uA single pin controls the LED display brightness by dsetting a reference current through a variable rerosistor connected t.
