(I) (I) ccoo Display Drivers :c!: DM8864, DM8865, DM8866 LED cathode drivers general description 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 interfaced from MOS • Inputs and outputs clustered for easy wiring • Drivers consume no standby power connection diag...
