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
