FEATURES SUMMARY
APPLICATION EXAMPLES
DESCRIPTION
The M5482 is a monolithic MOS integrated circuit
produced with an N-channel silicon gate technolo-
gy. 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 dis-
