DESCRIPTION
The SCF574X is a four digit, dot addressable 5x7 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 0.1" pin spacing.
The on-board CMOS has a 140 bit RAM, one bit associated with one
LED, each to generate User Defined Characters. In Power Down
Mode, quiescent current is <50 µA.
The SCF574X is designed for work with the serial port of most com-
mon 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 interference for portable com-
munication equipment or eliminate the visual sychronization effects
found in high vibration environments such as avionic equipment.

Low input enables data clocking
into 8-bit serial shift register.
When load goes high, the con-
tents of 8-bit serial shift register
will be decoded.
