TB62706BN/BF
TOSHIBA Bi−CMOS INTEGRATED CIRCUIT SILICON MONOLITHIC
TB62706BN,TB62706BF
16BIT SHIFT REGISTER, LATCHES & CONSTANT CURRENT DRIVERS
The TB62706BN, TB62706BF is specifically designed for LED
and LED DISPLAY constant current drivers.
This constant current output circuits is able to set up external
resistor (IOUT = 5~90 mA). (Note)
This IC is monolithic integrated circuit designed to be used
together with Bi−CMOS process.
The devices consist of 16bit shift register, latch, AND−GATE and
Constant Current Drivers.

[1] Output current (IOUT)
IOUT is set by the enternal resistor (R−EXT) as shown in Fig.1.
[2] Total supply voltage (VLED)
This device can operate 0.4~0.7V (VO).
When a higher voltage is input to the device, the excess voltage is consumed inside the device, that leads to
power dissipation.
In order to minimize power dissipation and loss, we would like to recommend to set the total supply voltage as
shown below,
VLED (total supply voltage) = VCE (Tr Vsat) + Vf (LED Forward voltage) + VO (IC supply voltage)
When the total supply is too high considering the power dissipation of this device, an additional R can
decrease the supply voltage (VO).
[3] Pattern layout
This device owns only one ground pin that means signal ground pin and power ground pin are common.
If ground pattern layout contains large inductance and impedance, and the voltage between ground and
LATCH, CLOCK terminals exceeds 2.5 V by switching noise in operation, this device may miss−operate. So we
would lile you to pay attention to pattern layout to minimize inductance.
