MM5450/5451

LED Display Driver

General Description

Features

• Continuous brightness control

• Serial data input

• No load signal requirement

• Enable (on MM5450)

• Wide power supply operation

• TTL compatibility

• 34 or 35 outputs, 15mA capability

• Alphanumeric capability

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.
