LTS-3403LWC Lite-On

LTS-3400L Series Features 0.8 inch (20.32mm) digit height. Continuous uniform segments. Choices of five bright colors-AlGaAs red/bright red/green/yellow/red orange. Low power requirement. Excellent characters appearance. High contrast. Hight brightness. Wide viewing angle. Solid state reliability. Categorized for luminous intensity. I.C. compatiable. Easy mounting on P.C. board or socket. Description The LTS-3400L series are 0.8 inch (20.32mm) height 7-single digit displays. All devices displays have gray face and white segments . The AlGaAs red 7-segment displays are designed for applications requiring low power consumption. They are tested and selected for their excellent low current characteristics to ensure that the segments are matched at low current. Driver current as low as 1mA 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 GaP substrate. The yellow and red orange series devices utilize LED chips which are made from GaAsP on a transparent GaP substrate.
