PS035 Datasheet, PDF (1/1 Pages) List of Unclassifed Manufacturers – 35-BIT LED DISPLAY DRIVER

35-BIT LED DISPLAY DRIVER
■ FEATURES
— CMOS technology
— Continuous brightness control
— Serial data input
— No LOAD signal required
— Optional external data enable and reset
— Wide power supply operation (3.5V to 10V)
— 34 or 35 outputs, 20mA sink capability
— Alphanumeric capability
Part No: 80-08-00004
Type: PS035
■ APPLICATIONS
— Products with alphanumeric LED displays such as digital clock, counter,
radio, multimeter, etc.
— Industrial control indicator or instrumentation readout
— Relay driver
■ 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.
