DESCRIPTION
The SCF574X is a four digit, dot addressable 5 x 7 dot
matrix, serial input, alphanumeric Intelligent Display
device. The four digits are packaged in a rugged, high
quality, optically transparent, plastic 22 pin DIP with
2.54 mm (0.1") pin spacing.
The on-board CMOS has a 140 bit RAM, one bit associ-
ated with one LED, each to generate User Defined Char-
acters. In Power Down Mode, quiescent current
is < 50 µA.
The SCF574X is designed for 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 (CLK SEL) pins
offer the user the capability to supply a high speed
external multiplex clock. This feature can minimize audio
in-band
equipment or eliminate the visual sychronization effects
found in high vibration environments such as avionic
equipment.
