MM5450/51

LED Display Driver

Features

General Description

• Continuous Brightness Control

• Serial Data Input

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.

• No Load Signal Requirement

• Enable (MM5450 Only)

• 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, 15 mA Capability

• Alphanumeric Capability

Applications

• Industrial Control Indicator

• Relay Driver

• Digital Clock, Thermometer, Counter, Voltmeter

• Instrumentation Readouts
