Descriptions
The LTS-2X01A, LTD-2000, LTC-2000 series are 0.28 inch (7.0mm) height single, dual triple and quadruple digit
displays.
The AlGaAs red seven segment displys are designed for applications requiring low power consumption. They are
tested and selected for the excellent low current characteristics to ensure that the segments are matched at low
current. Drive current as low as 1 mA per segment is available.
The AlGaAs red series devices utilize LED chips which are made from AlGaAs on a non-transparent GaAs
substrate. The bright red and green series devices utilize LED chips which are made from GaP on a transparent
GaPsubstrate. The yellow and red orange series devices utilize LED chips which are made from GaAsP on a
transparent GaP substrate. All devices have gray face and white segments.
