MM5450 - LED Display Driver

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.

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.
