Overview

DS8884A High Voltage Cathode Decoder Driver May 1986 DS8884A High Voltage Cathode Decoder Driver General Description The DS8884A is designed to decode four lines of BCD input and drive seven-segment digits of gas-filled readout displays All outputs consist of switchable and programmable current sinks which provide constant current to the tube cathodes even with high tube anode supply tolerance Output currents may be varied over the 0 2 mA to 1 2 mA range for multiplex operation The output current is adjusted by connecting an external program resistor (RP) from VCC to the program input in accordance with the programming curve Unused outputs must be tied to VCC Features Y Y Y Y Y Y Y Usabl...
