0.54"Alphanumeric LED Displays LTP-3784/3786 LTP-3784/3786 Series Features Package Dimensions 0.54 inch (13.8mm) digit height. Continuous uniform segments. Choices of five bright colors-AlGaAs red/bright red/ green/yellow/red orange. Low power requirements. Excellent character appearance. Wide viewing angle. Solid state reliability. Common anode or common cathode models. Categorized for luminous intensity. Easy mounting on P.C. board. Description The LTP-3784/3786 LTP-3784/3786 series are 0.54 inch (13.8mm) height 14-segment dual digit alphanumeric displays. The Displays have gray face and white segment. The AlGaAs red alphanumeric display 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. Drive current as low as 1 mA per segment is available. The AlGaAs red series device 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. Notes: All dimensions are in millimeters(inches). Tolerance: 0.25mm (0.010") unless otherwise noted.
