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 A.
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
