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.
