The HDSP‑331x/332E/333x/334x series are 7.62 mm (0.3 inch) LED seven‑segment displays that follow the industry‑standard size package and pinout. They are offered in common anode or common cathode configurations, with left‑hand and right‑hand decimal points, and are available in High Efficiency Red, Green, AlGaAs Red and Yellow colors for indoor use.
Mechanical options include optional color and intensity bins, and the datasheet provides detailed package dimensions, internal circuit diagrams, absolute maximum ratings, and electrical/optical characteristics. Contact information for Agilent regional support is listed at the end of the document.
