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

Note1: Voltage is ground referenced.
Note2: However, do not exceed 6V.
Note3: PCB condition 76.2 x 114.3 x 1.6 mm, Cu 30% (SEMI conforming)
Note4: The power dissipation decreases the reciprocal of the saturated thermal resistance (1/ Rth(j-a)) for each
degree (1°C) that the ambient temperature is exceeded (Ta = 25°C).

Note1: If the device is connected in a cascade and the tr/tf of the clock waveform increases due to deceleration of the clock
waveform,it may not be possible to achieve the timing required for data transfer. Please keep these timing conditions in mind
when designing your application.
