TOSHIBA CDMOS Integrated Circuit Silicon Monolithic

TC62D749CFG

16-Output Constant Current LED Driver (Output switching high-speed version)

The TC62D749CFG is a constant-current driver for LED and

LED display lighting applications.

The output current from each of the 16 outputs is

programmable via a single external resistor.

The TC62D749CFG contains a 16-channel shift register, a

16-channel latch, a 16-channel AND gate and a 16-channel

constant-current output.

Fabricated with a CMOS process, the TC62D749CFG allows

high-speed data transfer.

SSOP24-P-300-1.00B

Weight: 0.29 g (Typ.)

It operates with a 3.3- or 5-V power supply.

For detailed part naming conventions, contact your local Toshiba sales representative or distributor.

When the LED driver of high-speed output switching is used, back EMF may occur at the time of output OFF, and

output terminal voltage may rise. Please be careful. It is necessary to reduce inductance to prevent the back EMF. It

is possible to reduce inductance of a substrate by making the power supply for LED wiring shorter and wider

designing the layout pattern.
