LITE-ON TECHNOLOGY CORPORATION Property of Lite-on Only FEATURES 0.28 inch (7.0-mm) DIGIT HEIGHT CONTINUOUS UNIFORM SEGMENTS LOW POWER REQUIREMENT EXCELLENT CHARACTERS APPEARANCE HIGH BRIGHTNESS & HIGH CONTRAST WIDE VIEWING ANGLE SOLID STATE RELIABILITY CATEGORIZED FOR LUMINOUS INTENSITY LEAD-FREE PACKAGE (ACCORDING TO ROHS) DESCRIPTION The LTS-2301AWC is a 0.28 inch (7-mm) digit height single digit low current seven-segment display. This device uses AlGaAs red LED chips(AlGaAs epi on GaAs substrate). The display has gray face and white segments. This low current seven-segment display is designed to perform under low power consumption. It is tested and selected for it's excellent low current characteristics. It can be driven in low current condition and the segments are matched. This driving current as low as 1mA per segment is applicable. DEVICE PART NO. DESCRIPTION AlGaAs RED Common Cathode Rt.
