Description
TheA6282 device is designed for LED display applications. This CMOS device includes an input shift register, accompanying data latches, and 16 MOS constant current sink drivers.
The CMOS shift registers and latches allow direct interfacing with microprocessor-based systems. With a 3. 3 or 5 V logic supply, typical serial data i...
