16-Output Constant Current LED Driver (Output
switching standard-speed version)
TC62D748 series are an LED driver with a sink type constant
current output.
It is the best for lighting the LED module and the LED d
i
splay
.
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 AN
D
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 TC62D748 series are RoHS compatible.

Note1: Short circuiting an output pin to a power supply pin (Power-supply voltage V
DD
and LED anode power
supply), or short-circuiting the R
EXT pin to the GND pin will likely exceed the rating, which in turn may
result in smoldering and/or permanent damage. Please keep this in mind when determining the wiring
layout for the power supply and GND pins.
