DESCRIPTION
The SCD5580A (Red), SCD5581A (Yellow), SCD5582A
(Super-red), SCD5583A (Green) and SCD5584 (HEG)
are eight digit dot addressable 5 x 5 matrix, Serial Input,
Intelligent Display devices. The eight 3.68 mm (0.145")
high digits are packaged in a transparent, 7,62 mm (0.3")
pin spacing plastic DIP.
The on-board CMOS has a 200 bit RAM (one bit associ-
ated with one LED) 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 SCD558XA is designed to work with the Serial port of
most common microprocessors. The Clock I/O (CLK I/O)
and Clock Select (CLKSEL) pins offer the user the
capability to supply a high speed external 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 avionics equipment.
