DM8864 - LED cathode drivers

Key Features

  • The DM8864, DM8865 and DM8866 are cathode drivers for 9, 8, and 7 digit LED displays respectively. They are designed to interface between MOS calculator or clock circuits supplying 2.0 mA, and LED displays operating up to 50 mA in a multiplex mode. The DM8864 and DM8866 feature a "low battery" indicator driver which will light a decimal point whenever a 9.0V battery drops below 6.5V typical.
  • Used with 50 mA LED displays.
  • "Low battery voltage" indicator.
  • Directly int.
