MM5480 Product details

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 common 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
