DESCRIPTION
The LTD-322KD-31 is a 0.3 inch (7.62 mm) digit height dual digit
seven-segment display. This device utilizes AlInGaP Hyper Red LED chips,
which are made from AlInGaP on a non-transparent GaAs substrate, and has
a black face and white segments. This display is built by special reflector
material that can pass high-temperature soldering condition. Four sides are
painted black with black ink, and one side is painted black by black pen.

Note:
1. Luminous intensity is measured with a light sensor and filter combination that approximates
the CIE (Commision Internationale De L’Eclairage) eye-response curve.
2. Reverse voltage is only for IR test. It can not continue to operate at this situation
3. Crosstalk specification ≦ 2.5%
