General Description
The MM5450 and MM5451 are monolithic MOS integrated
circuits utilizing N-channel metal-gate low threshold en-
hancement mode and ion-implanted depletion mode devic-
es Theyare availablein 40-pin moldedor cavity dual-in-line
packages The MM5450MM5451is designedto drive com-
mon anode-separate cathode LED displaysA single pin
controls the LED display brightnessby settinga reference
current througha variable resistor connectedto VDD
Applications COPSTMor microprocessor displays Industrial control indicator Relay driver Digital clock thermometer counter voltmeter Instrumentation readouts
Features Continuous brightness control Serial data input No load signal required Enable (on MM5450) Wide power supply operation TTL compatibility 34or35 outputs15 mA sink capability Alphanumeric capability iJA DIP Boarde 49CW
