Industry Standard Pinout These devices use an industry standard size package and 15.24 mm (0.6 in.) DIP Leads on 2.54 mm (0.1 in.) pinout. Both the numeric and 1 overflow devices feature Centers a right hand decimal point. All devices are available as Choice of Colors either common anode or common cathode. AlGaAs Red, High Efficiency Red, Yellow, Green Excellent Appearance Applications Evenly Lighted Segments These displays are ideal for most applications. Pin for pin Mitered Corners on Segments equivalent displays are also available in a low current Gray Package Gives Optimum Contrast design. The low current displays are ideal for portable 50 Viewing Angle applica tions. For additional information see the Low Design Flexibility Current Seven Segment Displays data sheet.

These displays are recommended for high ambient light operation. Please refer to the HDSP-H10X/K12X AlGaAs and HDSP-555X HER data sheet for low current operation.Contrast Enhancement Mechanical The objective of contrast enhancement is to provide Specially developed plastics are used to optimize the good display readability in the end use ambient light. displays optical performance. These plastics restrict the The concept is to employ both luminance and chromi- solvents that may be used for cleaning. Only mixtures of nance contrast techniques to enhance the readability. Freon (F113) and alcohol should be used for vapor clean- This is accomplished by having the OFF dots blend into ing processes. Total immersion time in the vapors is two the display background and the ON dots stand out vividly minutes. Some suggested mixtures are Freon TE, Arklone against this same background. Therefore, these display A or K, or Genesolv DI-15 or DE-15. A 60C (140F) water devices are assembled with a gray package and matching cleaning process may also be used. This process includes encapsulating epoxy in the dots. a neutralizer rinse (3% ammonia solution or equivalent), a surfactant rinse (1% detergent solution or equivalent), a water rinse, and a thorough air dry. Room temperature Contrast enhancement may be achieved by using one of cleaning may be done with Freon T-E35 or T-P35, Ethanol, the following suggested filters: Isopropanol, or water with a mild detergent.
