MM5480 Datasheet Led Display Driver

Manufacturer: National

Overview: MM5480 LED Display Driver February 1995 MM5480 LED Display Driver General.

General Description

The MM5480 is a monolithic MOS integrated circuit utilizing N-channel metal gate low threshold enhancement mode and ion-implanted depletion mode devices It utilizes the MM5451 die packaged in a 28-pin package making it ideal for a 3 digit display The MM5480 is designed to drive mon anode-separate cathode LED displays A single pin controls the LED display brightness by setting a reference current through a variable resistor connected either to VDD or to a separate supply of 11V maximum Y Y Y Y Y No load signal required Wide power supply operation TTL patibility Alphanumeric capability 3 digit displays Applications Y Y Y Y Y
