DM75493 quad LED segment driver
general description
The OM75493 is a quad LED segment driver.
It is designed to interface between MOS IC's and LED's.
An external resistor is required for each segment to drive the output current which is approximately equal to O.
7V/RL and is relatively con.
tant, independent ot supply variations.
Blank· ing can be achievecj by taking the chip enable (CE) to a logical "1" level.
features
• Low voltage operation • Low input current for MOS compatibility • Low standby power • Display blahking capability • Output current regulation • Quad high gain circuits
