LB1276

The LB1276 is an LED driver array. By connecting this IC to LSI output pins whose output current capacity is small, LEDs can be lighted. It features high sensitivity (I N=80uAmax.) and IoUT=30mA driving capacity and is ideally suited for driving LEO indicators for use in commercial and industrial equipment.

The LB1276 possesses the features of high-sensitivity LED; driver array.
