The M5481 is a monolithic MOS integrated circuit produced with a N-channel silicon gate technology.
It uses the M5450 die packaged in a 20-pin plastic package copper frame, making it ideal for a 1-digit display. A single pin controls the LED display brightness by setting a reference current through a variable resistor connected either to VDD or to a separate supply of 13.2V maximum.
The M5481 is a pin-to-pin replacement of the NS MM 5481.
