DESCRIPTION
The LTM-8522G is a 0.56-inch (14.22-mm) numeric display
modules, and a built-in M5450 MOS integrated circuits. The
integrated circuit contains serial data input, 35 bits shift register.
34 LED driver output and a brightness control. This device
utilizes green LED chips, which are made from GaP on a
transparent GaP substrate, and has a gray face and white segments.
The MOS integrated circuits are produced with N-channel silicon
gate technology.
