DM8864
DM8864 is LED cathode drivers manufactured by National Semiconductor.
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 m A, and LED displays operating up to 50 m A 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 m A LED displays
- "Low battery voltage" indicator
- Directly interfaced from MOS
- Inputs and outputs clustered for easy wiring
- Drivers consume no standby power connection diagrams (Dual-In-Line Packages)
