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 respec-
tively. 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

Note 1: "Absolute MaXimum Ratings" are those values beyond which the ~afety of the deVice cannot be guaranteed. Except
for "Operating Temperature Range" they are not meant to Imply that the deVices should be operated at these limits. The
table of "Electrical Characteristics" provides conditions for actual device operation.
Note 2: Apply over O°C to +70°C operating temperature range.
