DESCRIPTION
The M5480 is a monolithic MOS integrated circuit
produced with a N-channel silicon gate technolo-
gy. It utilizes the M5451 die packaged in a 28-pin
plastic package making it ideal for a 3 1/2 digit dis-
paly. A single pin controls the LED dispaly bright-
ness by setting a reference current through a
variable resistor connected either to V
separate supply of 13.2V maximum.
The M5480 is a pin-to-pin replacement of the NS
MM 5480.
