Product details

Description

The A6285 is designed for LED display applications.

This BiCMOS device includes an On/Off shift register, a Dot Correction (DC) shift register, accompanying data latches, and 16 MOS constant-current sink drivers with active pull-ups that can be enabled or disabled as required by the application.

Features

3.0 to 5.5 V logic supply range.
Schmitt trigger inputs for improved noise immunity.
Power-On Reset (POR).
Up to 80 mA constant-current sinking outputs.
LED open circuit detection (LOD).
Dot correction (DC) for adjusting LED light intensity on each channel with 7-bit resolution.
Low-power CMOS logic and latches.
High data input rate up to 30 MHz.
Active output pull-ups with enable/disable.
20 ns typical staggering delay between outputs.
Int.
