DESCRIPTION
The SCE5780 (red), SCE5781 (yellow), SCE5782
(HER), SCE5783 (green), SCE5784 (HEG), SCE5785
(orange), and SCE5786 (InGaAlP red) are eight digit, dot
addressable 5 x 7 dot matrix, serial input, Intelligent Dis-
play devices. The eight 4.57 mm (0.180") high digits are
packaged in a rugged, high quality, optically transparent,
plastic 26 pin DIP with 7.62 mm (0.3") pin spacing.
The on-board CMOS has a 280 bit RAM, one bit associ-
ated with one LED, each to generate User Defined Char-
acters.
The SCE578X is designed to work with the serial port of
most common microprocessors. Data is transferred into
the display through the Serial Data Input (DATA), clocked
by the Serial Data Clock (SDCLK), and enabled by the
Load Input (LOAD).
The Clock I/O (CLK I/O) and Clock Select (CLKSEL) pins
offer the user the capability to supply a high speed exter-
nal multiplex clock. This feature can minimize audio
in-band interference for portable communication equip-
ment or eliminate the visual synchronization effects found
in high vibration environments such as avionic equipment.
The prescaler function allows for a higher speed external
multiplex clock when set to divide by 16.
