DESCRIPTIO N
The M5482 is a monolithic MOS integrated circuit
produced with an N-channel silicon gate technology. It utilizes the M5451 die pack aged 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 thro ugh a
variable resistor connected either to V
separate supply of 13.2V maximum.
