*All typical values specified at VDD = 5.0 V and TA = 25°C unless otherwise noted.
Notes:
±. These LED displays are categorized for luminous intensity, with the intensity category designated by a letter code on the back of the package.
7. Ti refers to the initial case temperature of the display immediately prior to the light measurement.
8. Dominant wavelength, ld, is derived from the CIE Chromaticity Diagram, and represents the single wavelength which defines the color of the device.
9. Categorized for color with the color category designated by a number on the back of the package.
