16-Output Constant Current LED Driver
The TB62747 series is comprised of constant-current drivers
designed for LEDs and LED panel displays.
The regulated current sources are designed to provide a
constant current, which is adjustable through one external
resistor.
The TB62747 series incorporates 16 channels of shift registers,
latches, AND gates and constant-current outputs.
Fabricated using the Bi-CMOS process, the TB62747 series
satisfies the system requirement of high-speed data transmission.
The TB62747 series is RoHS compatible

Note 1:
Note 2:
The latch circuit is a leveled-latch circuit. Please exercise precaution as it is not triggered-latch circuit.
Keep the SLAT pin is set to “L” to enable the latch circuit to hold data. In addition, when the SLAT pin
is set to “H” the latch circuit does not hold data. The data will instead pass onto output.
When the OE pin is set to “L” the OUT0 to OUT15 output pins will go ON and OFF in response to
the data. In addition, when the OE pin is set to “H” all the output pins will be forced OFF regardless of
the data.
