MM5451 - LED Display Driver

Download the MM5451 datasheet PDF. This datasheet also covers the MM5450 variant, as both devices belong to the same led display driver family and are provided as variant models within a single manufacturer datasheet.

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.

Key Features

  • Continuous Brightness Control.
  • Serial Data Input.
  • No Load Signal Requirement.
  • Enable (MM5450 Only).
  • Wide Power Supply Operation.
  • TTL Compatibility.
  • 34 or 35 Outputs, 15 mA Capability.
  • Alphanumeric Capability.

MM5450/51 LED Display Driver Features • Continuous Brightness Control • Serial Data Input • No Load Signal Requirement • Enable (MM5450 Only) • Wide Power Supply Operation • TTL Compatibility • 34 or 35 Outputs, 15 mA Capability • Alphanumeric Capability Applications • Industrial Control Indicator • Relay Driver • Digital Clock, Thermometer, Counter, Voltmeter • Instrumentation Readouts 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.
