DESCRIPTION

The M5482 is a monolithic MOS integrated circuit

produced with an N-channel silicon gate technol-

ogy. It utilizes the M5451 die packaged in a 20-pin

plastic package copper frame, making it ideal for a

2-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.
