Product Summary

The M5480B7 is a monolithic MOS integrated circuit produced with a N-channel silicon gate technology. The M5480B7 utilizes the M5451 die packaged in a 28-pin plas-tic package making it ideal for a 3 1/2 digit dispaly. A single pin controls the LED dispaly brightness by setting a reference current through a variable resistor connected either to VDD or to a separate supply of 13.2V maximum. The applications of the M5480B7 are microprocessor displays, industrial control indication, relay driver, instrumentation readouts.
