35-BIT 35-BIT LED DISPLAY DRIVER Part No: 80-08-00004 Type: PS035 PS035 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 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 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.
