TC62D749 series are an LED driver with a sink type constant
current output.
It is the best for lighting the LED module and the LED display.
This IC consists of a constant current output circuit of 16
outputs, a shift register of 16 bits, a latch of 16 bits, and 16 AND
gates.
The output current of 16 outputs can be set by one external
resistance.
Moreover, high-speed data transfer is possible by adoption of a
CMOS process.
This IC can operate with the power supply voltage of a 3.3 V
system and a 5 V system.
The TC62D749 series are RoHS compatible
