TB62706BNG/BFG
TOSHIBA Bi−CMOS INTEGRATED CIRCUIT
SILICON MONOLITHIC
TB62706BNG,TB62706BFG
16BIT SHIFT REGISTER, LATCHES & CONSTANT CURRENT DRIVERS
The TB62706BNG, TB62706BFG is specifically designed for LED
and LED DISPLAY constant current drivers.
This constant current output circuits is able to set up external
resistor (I
OUT
= 5~90 mA). (Note)
This I
C
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.

Note:
Latches are level sensitive, not rising edges sensitive and not syncronus CLOCK.
Input of LATCH−terminal to H Level, data passes latches, and input to L level, data hold latches.
Input of ENABLE−terminal to H level, all output (OUT0~15) do off.
