DESCRIPTION

The M5450 and M5451 are monolithic MOS inte-

grated circuits produced with an N-channel silicon

gate technology. They are available in 40-pin dual

in-line plastic packages.

A single pin controls the LED display brightness by

setting a reference current through a variable re-

sistor connected to VDD or to a separate supply of

13.2V maximum.
