A6285 Overview
The A6285 is designed for LED display applications. This BiCMOS device includes an On/Off shift register, a Dot Correction (DC) shift register, acpanying data latches, and 16 MOS constant-current sink drivers with active pull-ups that can be enabled or disabled as required by the application. The CMOS shift registers and latches allow direct interfacing with microprocessor-based systems.
