DESCRIPTION
The M5481 is a monolithic MOS integrated circuit
produced with a N-channel silicon gate technolo-
gy. 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 dis-
play 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.
