7 high-voltage and high current Darlington pairs
·
Each
pair is rated for 50V and 500mA
·
Input
pins can be triggered by +5V
·
All
seven Output pins can be connected to gather to drive loads up to (7×500mA)
~3.5A.
·
Can
be directly controlled by logic devices like Digital Gates, Arduino, PIC etc
·
Available
in 16-pin DIP, TSSOP, SOIC packages
