General Description

The MM5450 and MM5451 LED display drivers are

monolithic MOS IC’s fabricated in an N-Channel,

metal-gate

process.

The

technology

produces

low-threshold, enhancement-mode, and ion-implanted

depletion-mode devices.

A single pin controls the LED display brightness by

setting a reference current through a variable resistor

connected to the supply.
