DESCRIPTION

The SCD5580 (Red), SCD5581 (Yellow), SCD5582 (HER), SCD5583 (Green) and SCD5584 (HEG) are eight digit dot addressable 5x5 matrix, Serial Input, Intelligent Displays. The eight 0.145" (3.68 mm) high digits are packaged in a rugged, high quality optically transparent, standard 0.3" pin spacing 28 pin plastic DIP. The on-board CMOS has a 200 bit RAM, one bit associated with one LED, each to generate User Defined Characters. Due to the reduced LED count, power requirement and heat dissipation are reduced by 30%. Additionally in Power Down Mode quiescent current is <50 m The SCD558X is designed to work with the Serial port of most common microprocessors. The multiplex Clock I/O (CLK I/O) and multiplex Clock Select (CLK SEL ) pins offer the user the capability to supply a high speed external multiplex clock. This feature can minimize audio in-band interference for portable communication equipment or eliminate the visual synchronization effects found in high vibration environments such as avionic equipment Package Dimensions in inches (mm) 1.
