DM8887 Overview
The DM7887/DM8887 and DM7897/DM8897 ani designed to drive the individual anodes of a seven segment (cathodes) hlgh~voltage gas discharge panel In a time multiplexed fashion. When driven with appropriate input, signals, the driver will switch voltage and impedance levels at the anode. This will allow or prevent Ionization of gas around selected cathode in order to form a numeric display.
