MM5450/5451

LED Display Driver

General Description

Features

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.

•

Continuous brightness control

Serial data input

No load signal requirement

Enable (on MM5450)

Wide power supply operation

TTL compatibility

A single pin controls the LED display brightness by setting a

reference current through a variable resistor connected to

the supply.

34 or 35 outputs, 15mA capability

Alphanumeric capability

Applications

•

Industrial control indicator

Relay driver

Digital clock, thermometer, counter, voltmeter

Instrumentation readouts
