KB6282
Description
The KB6282 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 input rates can reach up to 30 MHz.
The LED drive current level can be set by a single external
resistor, selected by the application designer. A serial data
output permits cascading of multiple devices in applications
requiring additional drive lines.
The KB6282 is available in a variety of 24-terminal packages:
QFN (package ES) and eTSSOP (LP), which have an exposed
thermal pad, and SOIC (LW). All packages are lead (Pb) free
with 100% matte tin leadframe plating.
Applications include the following:
Monocolor, multicolor, or full-color LED display
Monocolor, multicolor, or full-color LED signboard
Display backlighting
Multicolor LED lighting
LED Driver
16-Channel Constant-Current LED Driver
