The DS7880 DS8880 is custom designed to decode four lines of BCD and drive a gas-filled seven-segment display tube Each output constitutes a switchable adjustable current sink which provides constant current to the tube segment even with high tube anode supply tolerance or fluctuation These current sinks have a voltage compliance from 3V to at least 80V typically the output current varies 1% for output voltage changes of 3 to 50V Each bit line of the decoder switches a current sink on or off as
