GENERAL DESCRIPTIONS
The PS035 is designed to drive either 4 or 5-digit, common anode alphanumeric
LED displays with the added benefit of requiring minimal interface with the
display or data source. Data is transferred serially via 2 signals: clock and
serial data. Data transfer without the added inconvenience of external LOAD
and RESET signal is accomplished by using a format of a leading "1" followed
by the allowed 35 data bits. Display brightness is determined by control of
the output current for LED displays. Typically, the output current is 36 times
greater that current flowing into the B.C. terminal.
