DESCRIPTION
●The M5450 and M5451 are monolithic MOS integrated circuits produced with an N-channel silicon gate technology. They are available in 40-pin dual in-line plastic packages. A single pin controls the LED display brightness by setting a reference current through a variable resistor connected to VDDor to a separate supply of 13.2V maximum.
●FEATURES SUMMARY
●■ M5450 34 OUTPUTS/15mA SINK
●■ M5451 35 OUTPUTS/15mA SINK
●■ CURRENT GENERATOR OUTPUTS (NO EXTERNAL RESISTORS REQUIRED)
●■ CONTINUOUS BRIGHTNESS CONTROL
●■ SERIAL DATA INPUT
●■ ENABLE (ON M5450)
●■ WIDE SUPPLY VOLTAGE OPERATION
●■ TTL COMPATIBILITY
●Application Examples:
●■ MICROPROCESSOR DISPLAYS
●■ INDUSTRIAL CONTROL INDICATOR
●■ RELAY DRIVER
●■ INSTRUMENTATION READOUTS
