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.

Descriptions
Communication checking error, when CEB is at the falling edge, it is high
level, while the rising edge is low level.
Power supply, operating voltage is 2~5V
Segment drive, drive current is22mA; When DATA is 0, LED output low
level; when DATA is 1, output is high impedance state
