DM8866
DM8866 is LED cathode drivers manufactured by National Semiconductor.
- Part of the DM8864 comparator family.
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) OUTPUTS OUTPUTS INPUTS TOPVIEW Order Number DM8864N See Package 29 OUTPUTS INPUTS TOPVIEW Order Number DM8865N See Package 25 typical application INPUTS TOPVIEW Order Number DM8866N See Package 25 . -_ _ _ _ _ _ _...._-o+90V LAST Ol Gl T MM6736DR...
