DM8885, MOS to high voltage cathode buffer

Display Drivers o ~ 00 00 00 en DM8885 MOS to high voltage cathode buffer general discription The DM8885 mterfaces MOS calculator or counterlatch-decoder-drlver CirCUits directly to sevensegment high-voltage gas-filled dlsplays_ The SIX inputs A, B, D, E, F, G are decoded to drive the seven segments of the tube.

Each output constitutes a sWltchable, adjustable current source which prOVides constant current to the tube segment, even With high tube anode supply tolerance or fluctuation.
