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
