TB62747AFG,C8,EL

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. It operates with a 3.3 or 5.0 V power supply.
