DESCRIPTION

The M5480 is a monolithic MOS integrated circuit

produced with a N-channel silicon gate technology.

It utilizes the M5451 die packaged in a 28-pin

dispaly. A single pin controls the LED dispaly bright-

ness by setting a reference current through a vari-

separate supply of 13.2V maximum.

The M5480 is a pin-to-pin replacement of the NS

MM 5480.
