SC16722
CASCADE LED DRIVER OF HEAVY CURRENT
DESCRIPTION
SC16722 is a chip special for LED driver. It utilizes advanced
CMOS technology and provides low power dissipation. This circuit
has the protecting circuit for all the inputs and outputs to avoid the
damage caused by the static discharge. And it has the ability of
driving load and features high noise immunity.
FEATURES
SOP-14-225-1.27
* 3 bits driving output (Max.=30mA)
* Provides the interface suited for cascade.
* Input compatible with 5V CMOS voltage.
* Maximum 15M serial clock frequency.
APPLICATION
* Lights decorations
* Outdoors lights
