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 V
13.2V maximum.
