Overview
SC16426 64-BIT LED STATIC DRIVER DESCRIPTION SC16426 is a LED driver circuit.
It features in few communication ports (4 ports are used for interaction communication with the single-chip microcomputer), strong anti-interference capability (automatic error correction for communication data), heavy current drive (driving 64 LED all together at most, each is 22mA), good uniformity of drive current and so on.
